Near-Death Experiences in patients with locked-in syndrome: Not always a blissful journey

Memories of Near-Death Experiences (NDEs) most often are recounted as emotionally positive events. At present, no satisfactory explanatory model exists to fully account for the rich phenomenology of NDEs following a severe acute brain injury. The particular population of patients with locked-in syndrome (LIS) provides a unique opportunity to study NDEs following infratentorial brain lesions. We here retrospectively characterized the content of NDEs in 8 patients with LIS caused by an acute brainstem lesion (i.e., “LIS NDEs”) and 23 NDE experiencers after coma with supratentorial lesions (i.e., “classical NDEs”). Compared to “classical NDEs”, “LIS NDEs” less frequently experienced a feeling of peacefulness or well-being. It could be hypothesized that NDEs containing less positive emotions might have a specific neuroanatomical substrate related to impaired pontine/paralimbic connectivity or alternatively might be related to the emotional distress caused by the presence of conscious awareness in a paralyzed body.     

A critique of Kellehear's transcendent society

Allan Kellehear argued that the otherworld society envisioned in near-death experiences (NDEs) is similar to utopian societies. However, his cultural analysis, based on 9 Mormon NDEs, did not reflect the diversity of near-death visions from other cultures. I suggest that these Mormon NDEs were neither as utopian as Kellehear assumed nor representative of contemporary NDE reports, and that a more complete analysis would reveal a variety of NDEs and otherworld visions reflecting the experiencers' sociocultural back-ground. Robert Bellah's model of religious evolution provides a model for charting the NDE's change over time and cultures, and allows us to differentiate the perennial features of the NDE from the transient culturally-determined ones — a first step in understanding the role of NDEs in the quest for an ideal society.Howard Mickel, Ph.D., formerly Chairman of the Department of Religion at Wichita State University, is currently Director of the Theta Project, an educational and research effort focusing on near-death and related experiences.     

A Rasch scaling validation of a ‘core’ near‐death experience

For those with true near‐death experiences (NDEs), Greyson's (1983, 1990) NDE Scale satisfactorily fits the Rasch rating scale model, thus yielding a unidimensional measure with interval‐level scaling properties. With increasing intensity, NDEs reflect peace, joy and harmony, followed by insight and mystical or religious experiences, while the most intense NDEs involve an awareness of things occurring in a different place or time. The semantics of this variable are invariant across True‐NDErs' gender, current age, age at time of NDE, and latency and intensity of the NDE, thus identifying NDEs as ‘core’ experiences whose meaning is unaffected by external variables, regardless of variations in NDEs' intensity. Significant qualitative and quantitative differences were observed between True‐NDErs and other respondent groups, mostly revolving around the differential emphasis on paranormal/mystical/religious experiences vs. standard reactions to threat. The findings further suggest that False‐Positive respondents reinterpret other profound psychological states as NDEs. Accordingly, the Rasch validation of the typology proposed by Greyson (1983) also provides new insights into previous research, including the possibility of embellishment over time (as indicated by the finding of positive, as well as negative, latency effects) and the potential roles of religious affiliation and religiosity (as indicated by the qualitative differences surrounding paranormal/mystical/religious issues).     

The Mystery of Frightening Transcendent Experiences: A Rejoinder to Nancy Evans Bush and Christopher Bache

In this essay, I review Christopher Bache's (1994) perinatal account of near-death experiences (NDEs) and suggest that it does not go far enough. I then present a new model, bliss/abyss, derived from the study of mysticism; show that pleasant and frightening NDEs can be accommodated within the model; and discuss the predictions that can be drawn from the new theoretical framework. The implication for near-death research is that there may be several types of frightening NDEs beyond the three types recently identified by Bruce Greyson and Nancy Evans Bush (1992). I emphasize understanding the powerful emotional force that ensures that all frightening experiences, whether NDEs, perinatal, or spontaneous, have a taste of hell. Extending Bush's intuition, I argue that both pleasant and frightening transcendent experiences intimate the ultimate reality through the colored glasses of bliss and horror respectively. Finally, I suggest areas for further research.     

Near-Death Experiences in a Multi-religious Hospital Population in Sri Lanka

Near-death experiences (NDEs) are a wide range of experiences that occur in association with impending death. There are no published studies on NDEs in general hospital populations, and studies have been mainly conducted on critically ill patients. We assessed the prevalence of NDEs and its associations in a multi-religious population in a general hospital in Sri Lanka. A randomised sample of patients admitted to the Colombo North Teaching Hospital was assessed using the Greyson NDE scale and clinical assessment. Out of total 826 participants, NDEs were described by 3%. Compared to the NDE-negative participants, the NDE-positive group had a significantly higher mean for age and a ratio of men. Women reported deeper NDEs. Patients of theistic religions (Christianity, Islam and Hinduism) reported significantly more NDEs compared to patients from the non-theistic religious group (Buddhism). NDE-positive patient group had significantly higher reporting of a feeling ‘that they are about to die’, the presence of loss of consciousness and a higher percentage of internal medical patients. This is the first time that NDEs are assessed in a general hospital population and NDEs being reported from Sri Lanka. We also note for the first time that persons with theistic religious beliefs reported more NDEs than those with non-theistic religious beliefs. Medical professionals need to be aware of these phenomena to be able to give an empathic hearing to patients who have NDE.     

Amazing Grace: The Healing Effects of Near-Death Experiences on Those Dying And Grieving

Kenneth Ring (1991) argued that near-death experiences (NDEs) act as compensatory gifts helping individuals cope with and understand life's difficulties. He saw NDEs as conferring amazing grace on individuals whose lives were spinning out of control toward self-destruction. Expanding on Ring's contention that NDEs can be seen as healing gifts, this study presents evidence of seven categorical situations where participating in or knowledge of NDEs and nearing-death awareness experiences serve as healing agents in facing one's own death or the death of a significant other. NDEs and nearing death awareness seem to free persons from paralyzing death anxiety and, consequently, allow them to focus on additional ways to help each other face dying and grieving.     

Different Kinds of Near-Death Experience: A Report on a Survey of Near-Death Experiences in Germany

This article provides a short summary of a representative survey on near-death experiences (NDEs) in Germany, which is the first of its kind in Europe. We tested several assumptions derived from previous research on NDEs, including the assumptions of a unified pattern of experience, the universality of the pattern, and the necessary link between NDEs and clinical death. We received replies from more than 2,000 persons, 4 percent of whom reported NDEs. The patterns of the NDEs did not seem to correspond to earlier findings: aside from being much more diverse, they also differed with respect to cultural variables, particularly the difference between religious interpretations and the differences between post-socialist East Germany and West Germany.     

A systematic analysis of distressing near-death experience accounts

ABSTRACT

Near-death experiences (NDEs) are usually associated with positive affect, however, a small proportion are considered distressing. We aimed to look into the proportion of distressing NDEs in a sample of NDE narratives, categorise distressing narratives according to Greyson and Bush’s classification (inverse, void or hellish), and compare distressing and “classical” NDEs. Participants wrote down their experience, completed the Memory Characteristics Questionnaire (assessing the phenomenology of memories) and the Greyson scale (characterising content of NDEs). The proportion of suicidal attempts, content and intensity of distressing and classical NDEs were compared using frequentist and Bayesian statistics. Distressing NDEs represent 14% of our sample (n?=?123). We identified 8 inverse, 8 hellish and 1 void accounts. The proportion of suicide survivors is higher in distressing NDEs as compared to classical ones. Finally, memories of distressing NDEs appear as phenomenologically detailed as classical ones. Distressing NDEs deserve careful consideration to ensure their integration into experiencers’ identity.     

The Near-Death Experience: Knowledge and Attitudes of College Students

There is a considerable literature documenting the effects of a near-death experience (NDE) on persons who actually undergo the experience, in terms of their attitudes and opinions about NDEs. However, investigations of how much nonexperiencers know about NDEs and their attitudes towards them are in short supply. This study examined the relationship in people who have not had an NDE between attitudes toward and knowledge of near-death experiences. Subjects were undergraduate students, with a mean age of 32 years. The Near-Death Phenomena Knowledge and Attitudes Questionnaire was employed to assess attitudes toward and knowledge of NDEs. Results indicated that both knowledge and attitudes were relatively normally distributed, and that level of knowledge significantly predicted attitudes towards NDEs, accounting for 34 percent of the common variance.     

A comparison of retrospective accounts of childhood near-death experiences with contemporary pediatric near-death experience accounts

I compared five childhood near-death experiences (NDEs) reported by adults and another five NDEs reported by minors, in terms of Ring's five NDE stages, Greyson's four NDE components, Moody and Perry's 12 NDE traits, Sabom's 16 general characteristics, and Gallup and Proctor's 10 basic positive experiences. In this combined pool of 47 NDE characteristics (which were interdependent), only two relating to time sense showed significant differences between the adults' retrospective reports of childhood NDEs and the children's contemporary NDE reports, and that number of differences would be expected by chance. This study therefore supports the claims of previous researchers that adults' retrospective reports of childhood NDEs are not embellished or distorted.     

Angels in near-death experiences

The literature on near-death experiences (NDEs) contains no substantive discussion of angels in NDEs, even though there are references to angels in several studies of these experiences. In this article I identify angels in NDEs and describe their functions in the NDE based on published NDE accounts. I conclude that angels are personages with whom the NDEr does not usually recall having previous acquaintance. Angels, serve as guides, messengers, or escorts in the NDE.This research was supported by a sabbatical leave granted by the Sabbatical Leave Commitee of Western New Mexico University.     

Is the Near-Death Experience Only N-Methyl-D-Aspartate Blocking?

Karl Jansen's interesting hypothesis that near-death experiences (NDEs) result from blockade of the N-methyl-D-aspartate receptor has several weaknesses. Some NDEs occur to individuals who are neither near death nor experiencing any event likely to upset cerebral physiology as Jansen proposed; thus his hypothesis applies only to a subset of NDEs that occur in catastrophic circumstances. For that subset, the clarity of NDEs and the clear memory for the experience afterward are inconsistent with compromised cerebral function. Jansen's analogy between NDEs and ketamine-induced hallucinations is weakened by the fact that most ketamine users do not believe the events they perceived really happened. Temporal lobe seizures do not resemble NDEs as Jansen postulated; they are confusional, rarely ecstatic, and never clear, as are NDEs, nor are they remembered afterward. Jansen's hypothesis assumes the standard scientific view that brain processes are entirely responsible for subjective experience; however, NDEs suggest that that concept of the mind may be too limited, and that in fact personal experience may continue beyond death of the brain.     

Commentary on Jansen's Paper

Karl Jansen raises a fundamental and exciting question: Is humankind's consciousness the result of neuronal function, or are there extra-cerebral aspects as well? While his neurotransmitter model of near-death experiences (NDEs) is well described, I find his supporting evidence weak. Methodological differences between studies of ketamine hallucinations and near-death experiences (NDEs) raise doubts about how similar those experiences are phenomenologically. While Jansen's model has electrifying implications, the data required to support his conclusions do not yet exist.     

Commentary on Allan Kellehear's “Near-death experiences and the pursuit of the ideal society”

Allan Kellehear's article raised four questions for me: (1) whether the near-death experience (NDE) presents enough data about the nature of a transcendent society for it to be a useful model for earthly societies; (2) the degree to which transcendent societies have to address the practical considerations of a material society; (3) whether NDEs are projections of experiencers' cultural concepts about the nature of the transcendent realm(s); and (4) the kind of hope offered by the growing awareness of the features of Western NDEs. I address these questions by referring to transcendent realm concepts and NDEs in the anthropological literature, particularly that of the North American Indian Prophet Movement.     

Response to Commentaries on "The Ketamine Model of the Near-Death Experience ..."

The commentators on my paper raised several interesting issues. Set and setting do influence drug effects, but they also influence near-death experiences (NDEs). Some NDEs are very anxiety-generating, just like some ketamine experiences, though frightening NDEs have been ignored by most researchers. High frequency, compulsive ketamine use is rare. While dimethyltryptamine (DMT) may induce NDEs, this is far from typical, while NDE-like effects are typical of ketamine. Rapidity of onset is not related to the capacity of a drug to induce NDEs. The reality of endopsychosins is doubtful, but the reality of N-methyl-D-aspartate (NMDA) blocking mechanisms is not. NDEs and dream sleep may involve similar mechanisms. Altered states of consciousness do not require a normally functioning brain. Finally, I discuss the possible evolutionary advantage of the NDE mechanism.     

Six Studies of Out-of-Body Experiences

Because of confusion between science and scientism, many people react negatively to the idea of scientific investigation of near-death experiences (NDEs), but genuine science can contribute a great deal to understanding NDEs and helping experiencers integrate their experiences with everyday life. After noting how scientific investigation of certain parapsychological phenomena has established a wider world view that must take NDEs seriously, I review six studies of a basic component of the NDE, the out-of-body experience (OBE). Three of these studies found distinctive physiological correlates of OBEs in the two talented persons investigated, and one found strong evidence for veridical, paranormal perception of the OBE location. The studies using hypnosis to try to produce OBEs demonstrated the complexity of a simple model that a person's mind is actually at an out-of-body location versus merely hallucinating being out, and require us to look at how even our perception of being in our bodies is actually a complex simulation, a biopsychological virtual reality.     

Gender and Trauma in the Near-Death Experience: An Epidemiological and Theoretical Analysis

In this article, I explore the nature of the fear-death experience (FDE) by way of an epidemiological analysis, and discuss the FDE as one of several causal theories of the near-death experience (NDE). I then pursue two hypotheses: (1) if the FDE model is correct, one would expect to find that a number of NDEs are preceded by traumatic experiences; and (2) if the FDE model is correct, one would expect to find that more NDEs are experienced by males than females. Chi-squared analyses on data from more than 500 NDE cases revealed that the first hypothesis cannot be rejected, while the second hypothesis can be rejected. I discuss the theoretical implications of these findings.     

Do Near-Death Experiences Provide a Rational Basis for Belief in Life after Death?

In this paper I suggest that near-death experiences (NDEs) provide a rational basis for belief in life after death. My argument is a simple one and is modeled on the argument from religious experience for the existence of God. But unlike the proponents of the argument from religious experience, I stop short of claiming that NDEs prove the existence of life after death. Like the argument from religious experience, however, my argument turns on whether or not there is good reason to believe that NDEs are authentic or veridical. I argue that there is good reason to believe that NDEs are veridical and that therefore it is reasonable to believe in the existence of what they seem to be experiences of, namely, a continued state of consciousness after the death of the body. I will then offer some comments on the philosophical import of NDEs, as well as reflections on the current state of contemporary philosophy in light of the neglect of this phenomenon.     

Near-Death and Out-of-Body Experiences in the Blind: A Study of Apparent Eyeless Vision

This article reports the results of an investigation into near-death and out-of-body experiences in 31 blind respondents. The study sought to address three main questions: (1) whether blind individuals have near-death experiences (NDEs) and, if so, whether they are the same as or different from those of sighted persons; (2) whether blind persons ever claim to see during NDEs and out-of-body experiences (OBEs); and (3) if such claims are made, whether they can ever be corroborated by reference to independent evidence. Our findings revealed that blind persons, including those blind from birth, do report classic NDEs of the kind common to sighted persons; that the great preponderance of blind persons claim to see during NDEs and OBEs; and that occasionally claims of visually-based knowledge that could not have been obtained by normal means can be independently corroborated. We present and evaluate various explanations of these findings before arriving at an interpretation based on the concept of transcendental awareness.     

Incidence of near-death experiences following attempted suicide

Near-death experiences (NDEs), profound subjective experiences occurring during a close brush with death and containing transcendental or mystical elements, have been reported to reduce suicidal ideation, despite their "romanticization" of death. Among 61 consecutive hospital admissions for attempted suicide, 16 patients (26.2%) reported NDEs precipitated by the attempt. NDEs were not significantly associated with any demographic factors. In light of the frequency of NDEs following attempted suicide, further studies are indicated in regard to the effect of those experiences on subsequent suicidal behavior.
