An exploratory study of alternative life experiences in comparison to transcendental near‐death experiences

AbstractThe term near‐death experience (NDE) generally refers to a state of altered consciousness that can occur during real or presumed near‐death circumstances and/or life‐threatening incidents. The NDE usually includes the impression of being conscious while out of and/or away from the physical body, often accompanied by other specific features. Furthermore, when the experient has the impression of being in a perceived locality that transcends the observable physical Earth, it is referred to by researchers as a transcendental NDE. Whereas transcendental NDEs have been widely studied, there is also another type of experience that can occur under similar life‐threatening conditions that I refer to as an alternative life experience (ALE), which consists of a perception of living another alternative life where the experient is aware of the self, but does not believe at the time of occurrence that they are either out of or away from their physical body. After providing a total of 15 examples, I note some similarities and differences between ALEs and transcendental NDEs while providing some qualitative and quantitative results, suggesting that ALEs might be similar to some aspects of transcendental NDEs despite their neglect in the study of altered states of consciousness during near‐death circumstances. I further postulate that ALEs might be subjective psychological experiences of dissociation and/or absorption. It is then pointed out that symptoms of derealization are a common ALE aftereffect and so an awareness of that association is stressed as having therapeutic importance.

Diversity and similarity of near-death experiences across cultures and history: implications for the survival hypothesis

While accounts of near-death experiences (NDEs) are found around the world and throughout history, descriptions of the phenomenon vary widely. Whether arguing for or against the survival hypothesis, most scholarly and scientific discussions of NDEs are predicated on seeing them as either a universal human phenomenon or as an entirely culturally-constructed one. This article will discuss the implications for the survival hypothesis of historical and cross-cultural NDEs, in all their diversity and similarity. On the scientific level, it will consider how the apparent universality of NDEs can be been enlisted to support both survival and materialist hypotheses. On the metaphysical level, this chapter will explore what kind of afterlife might be philosophically conceivable if we were to accept NDE narratives as reflecting genuine afterlife experiences—particularly given all their diversity.

Enhancement of perceptual and cognitive functions in near-death experience: A perspective from embodiment theories

The phenomenon of near-death experience (NDE) is attracting a growing attention among researchers of various fields. In this study, we looked at NDE from a cognitive perspective to find out how NDE events are embodied when people recall and describe them. We examined the descriptions of a group of people talking about what they had experienced in the state of NDE. Based on the gesture-as-simulated-action theory, we assumed that co-speech gestures occurring when people were talking about their experiences were physical realizations of mentally-simulated events. The results showed that the number of iconic and metaphoric gestures occurring with expressions referring to NDE events was significantly larger than those occurred with expressions referring to ordinary events. Based on these results, we suggest that embodied memory for NDE events is stronger than embodied memory for ordinary non-NDE events. NDE events are perceived, recalled, and embodied by strong activation of sensorimotor systems in a state of perceptual and cognitive enhancement, although sensorimotor systems seem to be unresponsive to sensory stimuli during NDE. Finally, based on theories of embodied cognition, we conclude that the enhancement of cognitive functions that takes place in the state of NDE is the result of enhancement in perceptual functions.

The gamma-band activity model of the near-death experience: a critique and a reinterpretation.

Near-death experience (NDE) is a transcendent mental event of uncertain etiology that arises on the cusp of biological death. Since the discovery of NDE in the mid-1970s, multiple neuroscientific theories have been developed in an attempt to account for it in strictly materialistic or reductionistic terms. Therefore, in this conception, NDE is at most an extraordinary hallucination without any otherworldly, spiritual, or supernatural denotations. During the last decade or so, a number of animal and clinical studies have emerged which reported that about the time of death, there may be a surge of high frequency electroencephalogram (EEG) at a time when cortical electrical activity is otherwise at a very low ebb. This oscillatory rhythm falls within the range of the enigmatic brain wave-labelled gamma-band activity (GBA). Therefore, it has been proposed that this brief, paradoxical, and perimortem burst of the GBA may represent the neural foundation of the NDE. This study examines three separate but related questions concerning this phenomenon. The first problem pertains to the electrogenesis of standard GBA and the extent to which authentic cerebral activity has been contaminated by myogenic artifacts. The second problem involves the question of whether agents that can mimic NDE are also underlain by GBA. The third question concerns the electrogenesis of the surge in GBA itself. It has been contended that this is neither cortical nor myogenic in origin. Rather, it arises in a subcortical (amygdaloid) location but is recorded at the cortex via volume conduction, thereby mimicking standard GBA. Although this surge of GBA contains genuine electrophysiological activity and is an intriguing and provocative finding, there is little evidence to suggest that it could act as a kind of neurobiological skeleton for a phenomenon such as NDE.

Dark resonance: On the possibility of resonance with death

The concept of resonance, introduced by Hartmut Rosa, denotes a vital relationship to the world and offers a starting point for discussing meaningfulness in peoples’ lives by serving as an antithesis to alienation. An unexplored aspect of the concept is the potential for resonance with death, which Rosa dismisses as an impossibility. This article challenges this view by introducing the term dark resonance, based on the ‘dark turn’ in the philosophy of nature. Dark resonance comes in (at least) two variants, both implying a transcendence of the self: (1) as reunion, an implosion of the self and an inwards movement, and (2) as release, an explosion of the self and an outwards movement. For both variants, the borders between self and environment and between life and death, becomes fuzzy, which also challenges the idea that resonance demands an experiencing subject. These variants are explored through examples from black metal, palliative care and near-death experiences. An implication is that we may need to broaden the scope of what can be seen as desirable ways of connecting to the world and acknowledge that there is potential for resonance also in dark thoughts, or, in some cases, even in death.

Fire Kasina advanced meditation produces experiences comparable to psychedelic and near-death experiences: A pilot study

Psychedelic-assisted therapy studies suggest that the induction of “mystical experiences” combined with psycho-therapy is a possible intervention for psychiatric illness. Advanced meditation may induce powerful experiences comparable to psychedelics. We investigated effects of an intensive meditation practice called Fire Kasina. Six individuals completed a retreat, and participated in an interview in which they described their experiences. They also completed the Revised Mystical Experience Questionnaire (MEQ), Hood Mystical Experience Scale (HME), and Cole's Spiritual Transformation Scale. Mean MEQ scores were 85 %, similar to prior observations of high-dose psilocybin and were stronger than moderate-dose psilocybin (t(5) = 4.41, p = 0.007, d = 1.80; W(5) = 21, p = 0.031). Mean HME scores were 93 %, exceeding levels reported for NDEs (mean 74 %) and high-dose psilocybin (mean 77 %). In qualitative analysis, experiences were described as the most intense of the individual's life, while subsequent transformational effects included substantial shifts in worldview.

Within-subject comparison of near-death and psychedelic experiences: acute and enduring effects.

Mystical-like states of consciousness may arise through means such as psychedelic substances, but may also occur unexpectedly during near-death experiences (NDEs). So far, research studies comparing experiences induced by serotonergic psychedelics and NDEs, along with their enduring effects, have employed between-subject designs, limiting direct comparisons. We present results from an online survey exploring the phenomenology, attribution of reality, psychological insights, and enduring effects of NDEs and psychedelic experiences (PEs) in individuals who have experienced both at some point during their lifetime. We used frequentist and Bayesian analyses to determine significant differences and overlaps (evidence for null hypotheses) between the two. Thirty-one adults reported having experienced both an NDE (i.e. NDE-C scale total score ≥27/80) and a PE (intake of lysergic acid diethylamide, psilocybin/mushrooms, ayahuasca, N,N-dimethyltryptamine, or mescaline). Results revealed areas of overlap between both experiences for phenomenology, attribution of reality, psychological insights, and enduring effects. A finer-grained analysis of the phenomenology revealed a significant overlap in mystical-like effects, while low-level phenomena (sensory effects) were significantly different, with NDEs displaying higher scores of disembodiment and PEs higher scores of visual imagery. This suggests psychedelics as a useful model for studying mystical-like effects induced by NDEs, while highlighting distinctions in sensory experiences.

Review of Appetite for Risk-What it is, Who has it and How I survived, by Robert R. Abbott.

Appetite for Risk is an autobiographical memoir of the author's life experiences. He vividly explains near-death experiences while maintaining humor, regaling about his escapades. It is thought-provoking to consider if human risky behavior is genetically predetermined.

Near-death experience: memory recovery during hypnosis

Increasing numbers of research studies have offered evidence regarding awareness of verified events during near-death experiences (NDEs) occurring during cardiac arrest and severely impaired brain function. The prevalence of patients reporting core NDEs under these conditions is reported as 10–12 %. One question that is often asked is why this percentage is low. Though it may be hypothesized that NDEs are limited to this low percentage of patients, it is also possible that more patients experience an NDE, but that memory is impaired sufficiently such that the NDE is not recalled. In this article I present a detailed and extensively verified case study of a woman, Stephanie Arnold, who experienced an NDE during the birth of her second child when she was 41 years old. The data provide evidence that supports the hypotheses 1) that during cardiac arrest an NDE may occur, but not be remembered until hypnotic regression therapy reveals extensive details of the events that could not have been perceived with the five senses, both in the operating room and elsewhere during resuscitation. 2) that there may also be pre-cognition of the events leading to the cardiac arrest, reported in clear detail, and 3) that NDEs lead to a fundamental transformation in an individual's understanding of the nature of consciousness, their quest for meaning and purpose, their concern for others, and their appreciation of life.

Death anxiety scale (DAS): internal structure and factorial invariance in Peruvian adults

Background Studies have this reported the presence of death anxiety, ranging from near-death experiences to physically ill people, to a simple thought about death, as well as when it is associated with states of loneliness. The Templer’s Death Anxiety Scale (DAS), based on Eysenk’s incubation theory, has been adapted and validated in different contexts and is still insufficient in countries such as Peru. This study aimed to determine the psychometric properties of the DAS, its internal structure, and factorial invariance. Methods An online scale was used in 1248 Peruvians aged between 18 and 70 years (M= 27.37, SD= 11.29) from all regions. DAS was validated using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, measurement invariance, and internal consistency (reliability). Results Psychometric properties were found with adequate values in its structure and validity based on the internal structure through exploratory factor analysis, where it was found that the components of the scale are interrelated and the data matrix is factorizable. model of three specific factors and a general factor is presented, which is consistent with the theory and has practical utility, revealing adequate statistical values that reflect acceptable levels of reliability. Finally, there was fairness according to sex and age group of the scale by means of factorial invariance analysis. Conclusions Our results indicate adequate psychometric properties and facilitate a better data collection process for future research.

Long-term transformational effects of near-death experiences

The purpose of this study was to deepen our understanding of the phenomenon of long-term transformational effects of near-death experiences (NDEs). Methods: Participants included 834 individuals who had experienced NDEs. We compared their responses with those of 42 individuals who had faced life-threatening situations (LTEs) without experiencing NDEs, aiming to discern whether transformations could be attributed solely to the proximity to death. We employed chi-square statistics to assess differences in aftereffects reported by the NDE and LTE-only groups. We also conducted a thematic analysis of the participants’ narratives to capture a more detailed account of the transformations experienced. Results: Our central finding reveals a significant transformation in values and spiritual attitudes among participants following their NDEs, as compared to individuals who were faced with life-threatening situations without an NDE. Key transformations include an enhanced belief in divinity and in the afterlife, a decreased fear of death, and increased levels of compassion. Participants also reported a stronger belief in the meaningfulness of life, and a profound shift in life priorities and values, emphasizing the increased importance of their spiritual or religious lives. Conclusions: The results support the notion that NDEs lead to a profound spiritual awakening and a reorientation towards life distinct from changes following LTEs without NDEs.

Suicide Following a Near-Death Experience.

Background: Sometimes during real or presumed life-threatening and/or near-death circumstances, an individual undergoes an altered state of consciousness referred to as a near-death experience (NDE). The prevalent position in the field of NDE research for the last several decades has been that such experiences result in positive antisuicidal attitudes and that it is highly unlikely that experients will try to kill themselves afterward. In addition, the important consideration of passive suicidal ideation is neglected in NDE research. Aims: To question the premature assumption that people are highly unlikely to die by suicide after an NDE. Method: Four case studies of suicide after an NDE are provided and examined. Results: Although important quantitative data are still needed, it can no longer be argued that people do not die by suicide after an NDE. Limitations: Only four cases were available for examination, and the degree of impact that the NDE had on their suicide is uncertain. Conclusion: Much more research is needed on suicide risk post NDE. In the meantime, the NDE should not be ignored in suicide assessments, but therapists and other relevant professionals need to be attentive to any possible indications of either active or passive suicidal ideation post NDE.

Phenomenological memory characteristics and impact of near-death experience in critically ill survivors: Observations at discharge and after a 1-year follow-up

BackgroundIt is not rare that intensive care unit (ICU) patients report unusual subjective experiences, ranging from a feeling of harmony with the environment to complex phenomena such as near-death experience (NDE). This 1-year follow-up study investigates the characteristics and potential global impact of the NDE memories recalled by ICU survivors. MethodWe prospectively enrolled 126 adult survivors of a prolonged (>7days) ICU stay (all etiologies), including 19 (15 %) who reported a NDE as identified by the Greyson NDE scale. The NDE group underwent a semi-structured interview one month later evaluating their memory characteristics and the associated life-threatening situation. One year after inclusion, all patients (regardless of whether they recalled an NDE) were contacted for a follow-up Greyson NDE scale assessment and questions about their ICU experience and opinions on death since discharge. ResultsThe Greyson NDE scale revealed that the most frequently reported features were altered time perception, heightened senses and life review, and the Greyson total scores did not evolve over time. NDE memories persisted, with a consequent number of phenomenological characteristics (e.g., visual details, emotions). One year post-ICU, two patients (18 %) of the NDE group and 12 (24 %) of the non-NDE group were less afraid of death. ConclusionsResults emphasize the clinical importance of interviewing all ICU patients to explore any memory after an ICU stay.

A Near-Death Experience Narrated by a Vepsian Woman

Abstract This article* focuses on the immediate near-death experience of an elderly woman living in traditional Vepsian culture. We analyse which universal, and which more culturally motivated features are present in her story narrated to us in 2018. We conclude that, despite the strong association with animistic beliefs in the informant’s everyday life, the experience is dominated by elements specific to vernacular Orthodox Christianity. The article presents a translation from Vepsian of a fragmentary personal experience narrative.

Undergraduate Students' Awareness of and Beliefs About Unusual End-of-Life Phenomena.

One hundred and forty undergraduate students responded to an online survey investigating their awareness of and beliefs about 12 unusual end-of-life phenomena (EOLP). Three quarters or more of the students had heard about the following EOLP: deathbed visions (75%), after-death communications (84%), near-death experiences (86%), and dying people choosing their time of death (88%). Students were least aware of the phenomena of shapes leaving the body after death (30%) and clocks or watches stopping when someone dies (26%). The two most common sources of students' knowledge about EOLP were from watching TV/movies (52-79%) and the internet (38-71%); the least common source was personal/direct experience with the EOLP (2-36%). Fifty-three percent of the students strongly agreed/agreed that EOLP are spiritual events, while 41% strongly agreed/agreed that there are medical explanations for EOLP. Suggestions for future research are offered.
