Near-death studies

Near-death studies is a field of psychology and psychiatry that studies the physiology, phenomenology and after-effects of the near-death experience (NDE). The field was originally associated with a distinct group of North American researchers that followed up on the initial work of Raymond Moody, and who later established the International Association for Near-death Studies (IANDS) and the Journal of Near-Death Studies. Since then the field has expanded, and now includes contributions from a wide range of researchers and commentators worldwide.

Near-death experience

The near-death experience is an experience reported by people who have come close to dying in a medical or non-medical setting. The aspect of trauma, and physical crises, is also recognized as an indicator for the phenomenon.[1] According to sources[2][3] it is estimated that near-death experiences are reported by five percent of the adult American population. According to IANDS,[4] surveys (conducted in USA, Australia and Germany) suggest that 4 to 15% of the population have had NDEs. Researchers study the role of physiological, psychological and transcendental factors associated with the NDE.[5] These dimensions are also the basis for the three major explanatory models for the NDE.

Some general characteristics of an NDE include subjective impressions of being outside the physical body; visions of deceased relatives and religious figures; transcendence of ego and spatiotemporal boundaries.[6][7] NDE researchers have also found that the NDE may not be a uniquely western experience. Commentators note that several elements and features of the NDE appears to be similar across cultures,[5][7][8][9][10][11] but the details of the experience (figures, beings, scenery), and the interpretation of the experience, varies between cultures.[7][8][10][12] However, a few researchers have challenged the hypothesis that near-death experience accounts are substantially influenced by prevailing cultural models.[13]

Elements of the NDE

According to the NDE-scale[10][14] a near-death-experience includes a few, or several, of the following 16 elements:

  1. Time speeds up or slows down.
  2. Thought-processes speed up.
  3. A return of scenes from the past.
  4. A sudden insight, or understanding.
  5. A feeling of peace or pleasantness.
  6. A feeling of happiness, or joy.
  7. A sense of harmony or unity with the universe.
  8. Confrontation with a brilliant light.
  9. The senses feel more vivid.
  10. An awareness of things going on elsewhere, as if by extrasensory perception (ESP).
  11. Experiencing scenes from the future.
  12. A feeling of being separated from the body.
  13. Experiencing a different, unearthly world.
  14. Encountering a mystical being or presence, or hearing an unidentifiable voice.
  15. Seeing deceased or religious spirits.
  16. Coming to a border, or point of no return.

In a study published in The Lancet van Lommel and colleagues[7] list ten elements of the NDE: Note a

  1. Awareness of being dead.
  2. Positive emotions.
  3. Out of body experience.
  4. Moving through a tunnel.
  5. Communication with light.
  6. Observation of colours.
  7. Observation of a celestial landscape.
  8. Meeting with deceased persons.
  9. Life review.
  10. Presence of border.

After-effects

According to sources the NDE is associated with a number of after-effects,[2][6][7][8][15][16][17][18] or life changing effects.[5][19] The effects, which are often summarized by researchers, include a number of value, attitude and belief changes[8][16] that reflect radical changes in personality,[8] and a new outlook on life and death, human relations, and spirituality.[2][6][15] Many of the effects are considered to be positive[2][19] or beneficial.[6] van Lommel and colleagues conducted a longitudinal follow-up research into transformational processes after NDEs and found a long-lasting transformational effect of the experience.[7]

However, not all after-effects are beneficial. The literature describes circumstances where changes in attitudes and behavior can lead to distress, psychosocial, or psychospiritual problems.[15][16][20]Note b Often the problems have to do with adjustment to the new situation following a near-death experience, and its integration into ordinary life.[16] Another category, so-called distressing or unpleasant near-death experiences, has been investigated by Greyson and Bush.[21]

Explanatory models

Explanatory models for the phenomenology and the elements of the NDE can, according to sources,[2][5][7][22][23][24] be divided into a few broad categories: psychological, physiological, and transcendental. Agrillo,[25] adopting a more parsimonious overview, notes that literature reports two main theoretical frameworks: (1) "biological/psychological" interpretation (in-brain theories), or (2) "survivalist" interpretation (out-of-brain theories). The research on NDEs often include variables from all three models. In a study published in 1990, Owens, Cook and Stevenson[22] presented results that lent support to all of these three interpretations.

Each model contains a number of variables that are often mentioned, or summarized, by commentators:

Psychological theories have suggested that the NDE can be a consequence of mental and emotional reactions to the perceived threat of dying,[5][7][19][22] or a result of expectation.[2] [9][11] Other psychological variables that are considered by researchers include: imagination;[2][11] depersonalization;[2][11] dissociation;[2][11] proneness to fantasy;[2][11] and the memory of being born.[11]

Physiological theories tend to focus on somatic, biological or pharmacological explanations for the NDE, often with an emphasis on the physiology of the brain. Variables that are considered, and often summarized by researchers, include: anoxia;[7][9] cerebral hypoxia;[5][19][26] hypercarbia;[5][19] endorphins;[5][8][9][15][19][26] serotonin[5][8][11][19][26] or various neurotransmitters;[2][11][15] temporal lobe dysfunction or seizures;[2][5][8][9][11][19][26][27] the NMDA receptor;[5][19][26] activation of the limbic system;[5][19] drugs;[5][9][19][26] retinal ischemia;[11] and processes linked to rapid eye-movement (REM) sleep or phenomena generated on the border between sleep and wakefullness.[2][11][27][28][29]

A third model, sometimes called the transcendental explanation,[2][5][7][8][22][23] considers a number of categories, often summarized by commentators, that usually fall outside the scope of physiological or psychological explanations. This explanatory model considers whether the NDE might be related to the existence of an afterlife;[22][23] a changing state of consciousness;[7] mystical (peak) experiences;[5] or the concept of a mind-body separation.[23]

Several researchers in the field, while investigating variables from all three models, have expressed reservations towards explanations that are purely psychological or physiological.[2][7][19][29][30][31] van Lommel and colleagues[7] have argued for the inclusion of transcendental categories as part of the explanatory framework. Other researchers, such as Parnia, Fenwick,[19] and Greyson,[10][31] have argued for an expanded discussion about the mind-brain relationship and the possibilities of human consciousness.

Research – history and background

Individual cases of NDEs in literature have been identified into ancient times.[32] In the 19th century a few efforts moved beyond studying individual cases - one privately done by Mormons and one in Switzerland. Up to 2005, 95% of world cultures have been documented making some mention of NDEs.[32] From 1975 to 2005, some 2500 self reported individuals in the US had been reviewed in retrospective studies of the phenomena[32] with an additional 600 outside the US in the West,[32] and 70 in Asia.[32] Prospective studies, reviewing groups of individuals and then finding who had an NDE after some time and costing more to do, had identified 270 individuals.[32] In all close to 3500 individual cases between 1975 and 2005 had been reviewed in one or another study. And all these studies were carried out by some 55 researchers or teams of researchers.[32]

Research on near-death experiences is mainly limited to the disciplines of medicine, psychology and psychiatry. Interest in this field of study was originally spurred by the research of such pioneers as Elisabeth Kübler-Ross (psychiatrist) and Raymond Moody (psychologist and M.D.), but also by autobiographical accounts, such as the books of George Ritchie (psychiatrist).[2][33][34] Kübler-Ross, who was a researcher in the field of Thanatology and a driving force behind the establishment of the Hospice System in the United States, reported on her interviews for the first time in her book "On Death and Dying. What the dying have to teach doctors, nurses, clergy, and their own families"(1969).[35][36][37] Raymond Moody, on the other hand, got interested in the subject at the start of his career. In the mid-seventies, while doing his medical residency as a psychiatrist at the University of Virginia, he conducted interviews with Near-Death Experiencers. He later published these findings in the book Life After Life (1976).[38] In the book Moody outlines the different elements of the NDE. Features that were picked up by later researchers. The book brought a lot of attention to the topic of NDEs.[8][10]

The late seventies saw the establishment of the Association for the Scientific Study of Near-Death Phenomena, an initial group of academic researchers, including John Audette, Raymond Moody, Bruce Greyson, Kenneth Ring and Michael Sabom, who laid the foundations for the field of Near-death studies, and carried out some of the first post-Moody NDE research.[39] The Association was the immediate predecessor of the International Association for Near-death Studies (IANDS), which was founded in the early eighties and which established its headquarters at the University of Connecticut, Storrs.[40] This group of researchers, but especially Ring, was responsible for launching Anabiosis, the first peer-reviewed journal within the field. The journal later became Journal of Near-Death Studies.[2]

However, even though the above-mentioned profiles introduced the subject of NDEs to the academic setting, the subject was often met with academic disbelief,[41] or regarded as taboo.[8] The medical community has been somewhat reluctant to address the phenomenon of NDEs,[8][10] and grant money for research has been scarce.[8] However, both Ring and Sabom made contributions that were influential for the newly established field. Ring published a book in 1980 called Life at Death: A Scientific Investigation of the Near-Death Experience.[42] This early research was followed up by new book in 1984 by the title Heading Toward Omega: In Search of the Meaning of the Near-Death Experience.[39][43] The early work of Michael Sabom was also bringing attention to the topic within the academic community. Besides contributing material to academic journals,[44] he wrote a book called Recollections of Death (1982)[45] which is considered to be a significant publication in the launching of the field.[39]

As research in the field progressed both Greyson and Ring developed measurement tools that can be used in a clinical setting.[14][46] Greyson has also addressed different aspects of the NDE, such as the psychodynamics of the experience,[47] the varieties of NDE,[3] the typology of NDEs[48] and the biology of NDEs.[49] In addition to this he has brought attention to the near-death experience as a focus of clinical attention,[15] suggesting that the aftermath of the NDE, in some cases, can lead to psychological problems.

The 1980s also introduced the research of Melvin Morse, another profile in the field of near-death studies.[50] Morse and colleagues[51][52] investigated near-death experiences in a pediatric population. They found that children reported NDEs that were similar to those described by adults. Morse later published two books, co-authored with Paul Perry, that were aimed at a general audience: Closer to the light: learning from children's near-death experiences (1990)[53] and Transformed by the light: the powerful effect of near-death experiences on people's lives (1992).[54] Another early contribution to the field was the research of British Neuro-psychiatrist Peter Fenwick, who started to collect NDE-stories in the 1980s. In 1987 he presented his findings on a television-program, which resulted in more stories being collected.[55][56] The responses from Near-death experiencers later served as the basis for a book published in 1997, "The Truth in the light", co-authored with his wife Elizabeth Fenwick.[57] Co-operating with other researchers, among others Sam Parnia, Fenwick has also published research on the potential relationship between cardiac arrest and Near-death Experiences.[5][19][26]

Early investigations into the topic of near-death experiences were also being conducted at the University of Virginia, where Ian Stevenson founded the Division of Personality Studies in the late sixties. The division went on to produce research on a number of phenomena that were not considered to be mainstream. In addition to near-death experiences this included: reincarnation and past lives, out-of-body experiences, apparitions and after-death communications, and deathbed visions.[10][58] Stevenson, whose main academic interest was the topic of reincarnation and past lives,[59][60] also made contributions to the field of near-death studies.[22][61] In a 1990-study, co-authored with Owens & Cook, the researchers studied the medical records of 58 people who believed they had been near death. The authors judged 28 candidates to actually have been close to dying, while 30 candidates, who merely thought they were about to die, were judged to not have been in any medical danger. Both groups reported similar experiences, but the first group reported more features of the core NDE-experience than the other group.[8][22]

Recently, the work of Jeffrey Long has also attracted attention to the topic of NDEs in both the academic, and the popular field.[62][63] In 2010 he released a book, co-authored with Paul Perry, called Evidence of the Afterlife: The Science of Near-Death Experiences. In the book Long presented results from research conducted over the last decade.[64] Research has also entered into other fields of interest, such as the mental health of military veterans. Goza studied NDEs among combat veterans. She found, among other things, that combat soldiers reported different, and less intense near-death experiences, compared to NDErs in the civilian population.[65][66]

The first decades of Near-death research were characterized by retrospective studies.[2][5][7][19][23][67][68] However, the 2000s marked the beginning of prospective studies in the field, both on the European and the American continent.

In a study from 2001, conducted at Southampton General Hospital, Parnia and colleagues found that 11.1% of 63 cardiac-arrest survivors reported memories of their unconscious period. Several of these memories included NDE-features.[5]Note c This study was the first in a series of new prospective studies using cardiac arrest criteria, and it was soon to be followed by the study of van Lommel and colleagues, also published in 2001. Pim van Lommel (cardiologist) was one of the first researchers to bring the study of NDEs into the area of Hospital Medicine. In 1988 he launched a prospective study that spanned 10 Dutch hospitals. 344 survivors of cardiac arrest were included in the study.[29] 62 patients (18%) reported NDE. 41 of these patients (12%) described a core experience. The aim of the study was to investigate the cause of the experience, and assess variables connected to frequency, depth, and content.[7]

Prospective studies were also taking place in the U.S. Schwaninger and colleagues[69] collaborated with Barnes-Jewish Hospital, where they studied cardiac arrest patients over a three-year period (April 1991 – February 1994). Only a minority of the patients survived, and from this group 30 patients were interviewable. Of these 30 patients 23% reported an NDE, while 13% reported an NDE during a prior life-threatening illness. Greyson[30] conducted a 30-month survey of patients admitted to the cardiac inpatient service of the University of Virginia Hospital. He found that NDEs were reported by 10% of patients with cardiac arrest and 1% of other cardiac patients.

In 2008 the University of Southampton announced the start of a new research-project named The AWARE (AWAreness during REsuscitation) study. The study was launched by the University of Southampton, but included collaboration with medical centres within the UK, mainland Europe and North America. The object of the study was to study the brain, and consciousness, during cardiac arrest, and to test the validity of out of body experiences and reported claims of lucidity (the ability to see and hear) during cardiac arrest.[18][70][71]

The first clinical paper from this project, described as a 4-year multi-center observational study, was published in 2014.[72][73][74][75][76][77] The study found that 9% of patients who completed stage 2 interviews reported experiences compatible with NDEs.

Psychometrics

Several psychometric instruments have been adapted to near-death research. Ring developed the Weighted Core Experience Index in order to measure the depth of NDEs,[14] and this instrument has been used by other researchers for this purpose.[78] The instrument has also been used to measure the impact of near-death experiences on dialysis patients.[79] According to some commentators[2] the index has improved consistency in the field. However, Greyson notes that although the index is a pioneering effort, it is not based on statistical analysis, and has not been tested for internal coherence or reliability.[14] In 1984 Ring developed an instrument called the Life Changes Inventory (LCI) in order to quantify value changes following an NDE. The instrument was later revised and standardized and a new version, the LCI-R, was published in 2004.[80]

Greyson[14] developed The Near-Death Experience Scale. This 16-item Scale was found to have high internal consistency, split-half reliability, and test-retest reliability[6][14] and was correlated with Ring's Weighted Core Experience Index. Questions formulated by the scale address such dimensions as: cognition (feelings of accelerated thought, or "life-review"), affect (feelings of peace and joy), paranormal experience (feelings of being outside of the body, or a perception of future events) and transcendence (experience of encountering deceased relatives, or experiencing an unearthly realm). A score of 7 or higher out of a possible 32 was used as the standard criterion for a near-death experience.[6] The scale is, according to the author,[6][14] clinically useful in differentiating NDEs from organic brain syndromes and nonspecific stress responses. The NDE-scale was later found to fit the Rasch rating scale model.[81] The instrument has been used to measure NDEs among cardiac arrest survivors,[5][72] coma survivors,[82] out-of-hospital cardiac arrest patients/survivors,[24][83][84] substance misusers,[85] and dialysis patients.[79]

In the late 1980s Thornburg developed the Near-Death Phenomena Knowledge and Attitudes Questionnaire.[86] The questionnaire consists of 23 true/false/undecided response items assessing knowledge, 23 Likert scale items assessing general attitudes toward near-death phenomena, and 20 Likert scale items assessing attitude toward caring for a client who has had an NDE.[87] Knowledge and attitude portions of the instrument were tested for internal consistency. Content validity was established by using a panel of experts selected from nursing, sociology, and psychology.[86] The instrument has been used to measure attitudes toward, and knowledge of, near-death experiences in a college population,[88] among clergy,[89] among registered psychologists,[86] and among hospice nurses.[87]

Greyson has also used mainstream psychological measurements in his research, for example The Dissociative Experiences Scale;[16] a measure of dissociative symptoms, and The Threat Index;[90] a measure of the threat implied by one's personal death.

Near death studies community

Research organizations and academic locations

The field of near-death studies includes several communities that study the phenomenology of NDEs. The largest of these communities is IANDS, an international organization based in Durham, North-Carolina, that encourages scientific research and education on the physical, psychological, social, and spiritual nature and ramifications of near-death experiences. Among its publications we find the peer-reviewed Journal of Near-Death Studies, and the quarterly newsletter Vital Signs.[91][92] The organization also maintains an archive of near-death case histories for research and study.[93]

Another research organization, the Louisiana-based Near Death Experience Research Foundation, was established by radiation oncologist Jeffrey Long in 1998.[62][63][94] The foundation maintains a web-site, also launched in 1998, and a database of more than 1,600 cases, which is currently the world's largest collection of near-death reports. The reports come directly from sources all across the world.[63]

A few academic locations have been associated with the activities of the field of near-death studies. Among these we find the University of Connecticut (US),[6] Southampton University (UK),[70] University Of North Texas (US)[65] and the Division of Perceptual Studies at the University of Virginia (US).[10][13][68]

Conferences

IANDS holds conferences, at regular intervals, on the topic of near-death experiences. The first meeting was a medical seminar at Yale University, New Haven (CT) in 1982. This was followed by the first clinical conference in Pembroke Pines (FL), and the first research conference in Farmington (CT) in 1984. Since then conferences have been held in major U.S. cities, almost annually.[95] Many of the conferences have addressed a specific topic, defined in advance of the meeting. In 2004 participants gathered in Evanston (IL) under the headline:"Creativity from the light".[33][96] A few of the conferences have been arranged at academic locations. In 2001 researchers and participants gathered at Seattle Pacific University.[97] In 2006 the University of Texas MD Anderson Cancer Center became the first medical institution to host the annual IANDS conference.[98]

The first international medical conference on near-death experiences was held in 2006.[29] Approximately 1.500 delegates, including people who claim to have had NDEs, were attending the one-day conference in Martigues, France. Among the researchers attending the conference were anaesthetist and intensive care doctor Jean-Jacques Charbonnier, and pioneering researcher Raymond Moody.[99]

Relevant publications

IANDS publishes the quarterly Journal of Near-Death Studies, the only scholarly journal in the field. The Journal is cross-disciplinary, is committed to an unbiased exploration of the NDE and related phenomena, and welcomes different theoretical perspectives and interpretations that are based on scientific criteria, such as empirical observation and research.[100] IANDS also publishes Vital Signs, a quarterly newsletter that is made available to its members and that includes commentary, news and articles of general interest.

One of the first introductions to the field of near-death studies was the publication of a general reader: The Near-Death Experience: Problems, Prospects, Perspectives. The book was published in 1984 and was an early overview of the field.[101] In 2009 Praeger Publishers published the Handbook of Near-Death Experiences: thirty years of investigation, a comprehensive critical review of the research carried out within the field of near-death studies.[32][102] 2011 marked the publication of Making Sense of Near-Death Experiences: A Handbook for Clinicians.[103] The book is a multi-author text which describes how the NDE can be handled in psychiatric and clinical practice.[104]

Recognition and criticism

Skepticism towards the findings of near-death studies, and the validity of the near-death experience as a subject for scientific study, has been widespread. According to Knapton, in The Daily Telegraph,[105] the subject was, until recently, considered to be controversial. Both scientists and medical professionals have, in general, tended to be skeptical.[8][106][107] According to commentators in the field[41] the early study of Near-death experiences was met with "academic disbelief". Acceptance of NDEs as a legitimate topic for scientific study has improved,[8] but the process has been slow.[10] According to literature[2] "psychiatrists have played a role in the recognition of the "near-death" phenomenon as well as popularization of the subject and subsequent research".

Skeptics have remarked that it is difficult to verify many of the anecdotal reports that are being used as background material in order to outline the features of the NDE.[8][62]

Internet Infidels paper editor, and commentator, Keith Augustine has criticized near-death research for oversimplifying the role of culture in afterlife beliefs. He has also exposed weaknesses in methodology, paucity of data, and gaps in arguments. Instead of a transcendental model of NDEs, which he does not find plausible, he suggests that NDEs are products of individuals' minds rather than windows into a transcendental reality.[108][109] His criticism has been answered by Greyson[109] who suggests that the materialist model favored by Augustine is supported by even fewer data than the "mind-brain separation model" favored by many researchers within the field of near-death studies.

The findings of NDE-research has been contested by several writers in the fields of psychology and neuroscience. Susan Blackmore[62] has contested the findings of NDE-research, and has instead argued in favour of a neurological explanation. Psychologist Christopher French[23][67] has reviewed several of the theories that have originated from the field of Near-death studies. This includes theories that present a challenge to modern neuroscience by suggesting a new understanding of the mind-brain relationship in the direction of transcendental, or paranormal, elements. In reply to this French argues in favour of the conventional scientific understanding, and introduces several non-paranormal factors, as well as psychological theory, that might explain those near-death experiences that defy conventional scientific explanations. However, he does not rule out a future revision of modern neuroscience, awaiting new and improved research procedures.

Jason Braithwaite, a Senior Lecturer in Cognitive Neuroscience in the Behavioural Brain Sciences Centre, University of Birmingham, issued an in-depth analysis and critique of the survivalist's neuroscience of some NDE researchers, concluding, "it is difficult to see what one could learn from the paranormal survivalist position which sets out assuming the truth of that which it seeks to establish, makes additional and unnecessary assumptions, misrepresents the current state of knowledge from mainstream science, and appears less than comprehensive in its analysis of the available facts."[110]

Martens[84] noted the "lack of uniform nomenclature", and "the failure to control the studied population with an elimination of interfering factors", as examples of criticism directed towards near-death research.

But criticism of the field has also come from commentators within its own ranks. In an open letter to the NDE-community Ring has pointed to the "issue of possible religious bias in near-death studies". According to Ring the field of near-death studies, as well as the larger NDE-movement, has attracted a variety of religious and spiritual affiliations, from a number of traditions, which makes ideological claims on behalf of NDE-research. In his view this has compromised the integrity of research and discussion.[39]

Bilocation

Bilocation, or sometimes multilocation, is an alleged psychic or miraculous ability wherein an individual or object is located (or appears to be located) in two distinct places at the same time.The concept has been used in a wide range of historical and philosophical systems, ranging from early Greek philosophy to modern religious stories, occultism and magic.

(Charles) Bruce Greyson (born October 1946) is Professor Emeritus of Psychiatry and Neurobehavioral Sciences at the University of Virginia. He is co-author of Irreducible Mind (2007) and co-editor of The Handbook of Near-Death Experiences (2009). Greyson has written many journal articles, and has given media interviews, on the subject of near death experiences.

Institut Métapsychique International

The Institut Métapsychique International (IMI) is a French parapsychological organization that studies paranormal phenomena. It was created in 1919 by Jean Meyer, Gustav Geley and Professor Rocco Santoliquido.Notable past presidents have included Charles Richet (1930-1935) and René Warcollier (1950-1962). Eugéne Osty served as a director (1925-1938).

International Association for Near-Death Studies

The International Association for Near-Death Studies (IANDS) is a non-profit organization based in Durham, North Carolina in the United States, associated with the academic field of near-death studies.

The Association was founded in the US in 1981, in order to study and provide information on the phenomena of the near death experience (NDE). Today it has grown into an international organization, which includes a network of more than 50 local interest groups, and approximately 850 members worldwide. Local chapters, and support groups, are established in major U.S cities. IANDS also supports and assists near-death experiencers (NDErs) and people close to them. In one of its publications the organization has formulated its vision as one of building "global understanding of near-death and near-death-like experiences through research, education, and support".

Journal of Near-Death Studies

The Journal of Near-Death Studies is a quarterly peer-reviewed academic journal devoted to the field of near-death studies. It is published by the International Association for Near-Death Studies.The journal's founding editor-in-chief was Kenneth Ring. Subsequent editors were Bruce Greyson and Janice Holden.

Journal of Parapsychology

The Journal of Parapsychology is a biannual peer-reviewed academic journal covering research on psi phenomena, including telepathy, clairvoyance, precognition, and psychokinesis, as well as human consciousness in general and anomalous experiences.

It was established in April 1937 by Joseph Banks Rhine (Duke University). It is published by the Rhine Research Center and the current editor-in-chief is Etzel Cardeña (Lund University). The journal is abstracted and indexed in PsychINFO. It publishes research reports, theoretical discussions, book reviews, and correspondence, as well as the abstracts of papers presented at the Parapsychological Association's annual meeting.

Kenneth Ring

Kenneth Ring (born 1936) is Professor Emeritus of psychology at the University of Connecticut, and a researcher within the field of near-death studies.

Life After Life (book)

Life After Life is a 1975 book written by psychiatrist Raymond Moody. It is a report on a qualitative study in which Moody interviewed 150 people who had undergone near-death experiences (NDEs). The book presents the author's composite account of what it is like to die. On the basis of his collection of cases, Moody identified a common set of elements in NDEs:

(a) an overwhelming feeling of peace and well-being, including freedom from pain.

(b) the impression of being located outside one's physical body.

(c) floating or drifting through darkness, sometimes described as a tunnel.

(d) becoming aware of a golden light.

(e) encountering and perhaps communicating with a "being of light".

(f) having a rapid succession of visual images of one's past.

(g) experiencing another world of much beauty.

Life After Life sold more than 13 million copies, was translated into a dozen foreign languages and became an international best seller, which made the subject of NDEs popular and opened the way for many other studies.

Mind over matter

Mind over matter is a phrase that has been used in several contexts, such as mind-centric spiritual doctrines, parapsychology, and philosophy.

Mirriam Webster Dictionary defines mind as "the element or complex of elements in an individual that feels, perceives, thinks, wills, and especially reasons" and mind over matter as able to; "a situation in which someone is able to control a physical condition, problem, etc., by using the mind".

Near-death experience

A near-death experience (NDE) is a personal experience associated with death or impending death. When positive, such experiences may encompass a variety of sensations including detachment from the body, feelings of levitation, total serenity, security, warmth, the experience of absolute dissolution, and the presence of a light. When negative, such experiences may include sensations of torment and torture. NDEs are a recognized part of some transcendental and religious beliefs in an afterlife.Different models have been described to explain NDEs. Neuroscience research suggests that an NDE is a subjective phenomenon resulting from "disturbed bodily multisensory integration" that occurs during life-threatening events.

Outline of parapsychology

Parapsychology is a field of research that studies a number of ostensible paranormal phenomena, including telepathy, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation, and apparitional experiences.

Oxford Phasmatological Society

The Oxford Phasmatological Society was an organisation from Oxford that investigated paranormal phenomena. It lasted from 1879-1885. It is considered the oldest psychical society in existence.It was founded by Charles Oman, Henry Nicholas Ridley and F. C. S. Schiller. Similar to the later formed Society for Psychical Research it collected and investigated reports of ghosts, hauntings and psychic phenomena.Meetings were held in the rooms of Schiller at Balliol College. Arthur Headlam was a President of the society.

Pam Reynolds case

Pam Reynolds Lowery (1956 – May 22, 2010), from Atlanta, Georgia, was an American singer-songwriter. In 1991, at the age of 35, she stated that she had a near-death experience (NDE) during a brain operation performed by Robert F. Spetzler at the Barrow Neurological Institute in Phoenix, Arizona. Her experience is one of the most widely documented in near-death studies because of the circumstances under which it happened. Reynolds was under close medical monitoring during the entire operation. During part of the operation she had no brain-wave activity and no blood flowing in her brain, which rendered her clinically dead. She claimed to have made several observations during the procedure which later medical personnel reported to be accurate.

This near-death experience claim has been considered by some to be evidence of the survival of consciousness after death, and of a life after death. However, others have pointed to prosaic and conventional means as possible explanations. Reynolds died from heart failure, on Saturday May 22, 2010, age 53 at Emory University Hospital, in Atlanta, Georgia.

Penny Sartori

Penny Sartori is a British medical researcher in the field of near-death studies.

Poltergeist

In ghostlore, a poltergeist (; German for "noisy ghost" or "noisy spirit") is a type of ghost or spirit that is responsible for physical disturbances, such as loud noises and objects being moved or destroyed. They are purportedly capable of pinching, biting, hitting, and tripping people. Most accounts of poltergeists describe the movement or levitation of objects such as furniture and cutlery, or noises such as knocking on doors.

They have traditionally been described as troublesome spirits who haunt a particular person instead of a specific location. Such alleged poltergeist manifestations have been reported in many cultures and countries including the United States, Pakistan, India‚ Japan, Brazil, Australia, and most European nations. Early accounts date back to the 1st century. Forms of spiritual harassment became more common in the early 1600s.

Psionics

Psionics is the study of paranormal phenomena in relation to the application of electronics. The term comes from psi (“psyche”) and the -onics from electronics (machine). It is closely related to the field of radionics. There is no scientific evidence that psionic abilities exist.

Psychometry (paranormal)

Psychometry (from Greek: ψυχή, psukhē, "spirit, soul" and μέτρον, metron, "measure"), also known as token-object reading, or psychoscopy, is a form of extrasensory perception characterized by the claimed ability to make relevant associations from an object of unknown history by making physical contact with that object. Supporters assert that an object may have an energy field that transfers knowledge regarding that object's history.There is no scientific evidence that psychometry exists and the concept has been widely criticized.

Pyrokinesis

Pyrokinesis is the purported psychic ability allowing a person to create and control fire with the mind. There is no conclusive evidence that pyrokinesis is a real phenomenon. Alleged cases are hoaxes, the result of trickery.

Rhine Research Center

The Rhine Research Center is an independent, non-profit parapsychology research center that takes a scientific approach to anomalous phenomena and exceptional human experience. According to the mission statement, the "Rhine's mission is to advance the science of parapsychology, to provide education and resources for the public, and to foster a community for individuals with personal and professional interest in PSI." It is the successor to the Parapsychology Laboratory at Duke University.In 1965, when J. B. Rhine reached mandatory retirement age, he left Duke University and founded an independent non-profit organization called the Foundation for Research on the Nature of Man. The current research center is a successor to this organization, and it is no longer affiliated with Duke University. The Rhine Research Center continues to conduct parapsychology research today, but it also provides online courses, educational events, and holds meetings for people interested in parapsychology and psi phenomena. The current president is Barbara Ensrud.
