Near-Death Experience VERIFIED

BG: Well I had no concept of anything spiritual before and I was convinced that death was the end. I no longer believe that. But I don't know what to believe now. Because again, experiencers say it can't be put into words. So I don't know what happens after death but I think something happens.

BG: Right, and some people who have near death experiences talk about seeing their deceased loved ones. Now you can just say that's wishful thinking, but sometimes they see deceased people who were not yet known to have died, and that's kind of hard to explain away.

Of 567 subjects, 213 or about 38% experienced sustained return of spontaneous circulation, meaning their pulse was restored for 20 minutes or longer. Only 53, or fewer than 10% of the participants, lived to be discharged from the hospital.

The research also included a cross-sectional study to make up for the fact that so few people lived following cardiac arrest in the study conducted in hospitals. This larger population of survivors provided self-reports of their experiences.

From the 126 cardiac survivors who provided self-reports about their experiences, five themes emerged. Some participants recalled feeling the impact of CPR on their bodies or hearing the medical team talk. Others recalled activities in the intensive care unit following CPR.

In 2008, a large-scale study involving 2060 patients from 15 hospitals in the United Kingdom, United States and Austria was launched. The AWARE (AWAreness during REsuscitation) study examined the broad range of mental experiences in relation to death. Researchers also tested the validity of conscious experiences using objective markers for the first time in a large study to determine whether claims of awareness compatible with out-of-body experiences correspond with real or hallucinatory events. Results of the study have been published in the journal Resuscitation and are now available online. The study concludes:

The description of a NDE using closed scales can result in the overlooking of relevant features that might have been experienced by NDErs but that are not listed in NDE questionnaires. Therefore, this study aims to explore the interest of a qualitative approach, specifically thematic analysis, to better portray NDEs that follow a cardiac arrest based on self-reported narratives.

The study was approved by the ethics committee of the Faculty of Medicine of the University of Liège. NDErs were recruited via the websites, the appearances in local media and the publications of the International Association for Near-Death Studies (IANDS France) and the Coma Science Group (GIGA Research Center, University and University Hospital of Liège, Belgium). Participants who contacted us indicated their consent by signing a written consent form. They then completed questionnaires requesting socio-demographic information (gender and age at interview), their age when they experienced the NDE, the time elapsed since the NDE and if the NDE has occurred during a life threatening event.

The length of the narratives varied from 4 lines to 3 pages. The analysis conducted on the 34 narratives allowed us to distinguish 11 main themes, among which we identified 10 time-bounded themes and 1 transversal theme. A time-bounded theme refers to an event that is relatively isolated within narratives and only occurs during a part of the experience, whereas a transversal theme characterizes the whole experience and is not described as an isolated moment. Moreover, the transversal theme generally appeared in narratives as the result of a retrospective consideration and as a comment of self-reflection on the experience. Arbitrarily selected illustrative verbatim are given in Table 3. Themes are detailed in the paragraphs below.

Light: Considering all narratives, 25 NDErs mentioned seeing a light. This light was attached to a feeling of attractiveness for 10 NDErs. 2 NDErs felt enveloped in this light. The description of the light comprised the following characteristics: intense (n = 16), white (n = 15), indescribable/unusual (n = 5), soft and diffuse (n = 3), not dazzling (n = 3), and yellow (n = 1). The physical sensations reported during this experience were an absence of body (n = 3) and an absence of pain (n = 1). NDErs expressed a feeling of happiness, serenity and tranquility (n = 15). The origin of the light was at the end of a tunnel or a corridor (n = 9), diffused (it came from everywhere; n = 7), or from an unknown origin (n = 1).

Hyperlucidity: 14 NDErs reported a feeling of power and extreme lucidity. Hyperlucidity was associated with absolute clarity/understanding (n = 3), the feeling of being a genius (n = 2), clear and quick wit (n = 2), or exceptional intelligence (n = 1). This experience was in some cases accompanied by a physical release (n = 4). 5 NDErs described this experience as being accompanied by a sense of power and omniscience: direct control over the thoughts of others (n = 2), omnipotence (n = 2), or having an answer to everything (n = 1). 3 NDErs linked this supreme intelligence to the fact of being united with everything that surrounded them, to the global and universal character of this theme. This experience was associated with a feeling of well-being (n = 6), a lack of physical pain (n = 4), astonishment (n = 4), and an inability to describe the feeling (n = 1).

Description of scenes: 14 NDErs provided a detailed description of the setting in which they were immersed. 6 NDErs highlighted the indescribable aspect of the place (i.e., they showed difficulties in finding words). 4 NDErs evoked the idea of nature (e.g., vast meadow). This experience was accompanied by an intense feeling of well-being (n = 10), a feeling of infinity (n = 5), a lack of pain (n = 4), astonishment (n = 3), and fear (n = 1).

Near-death experiences, or NDEs, are significant psychological events that occur close to actual or perceived impending death. Commonly reported aspects of NDEs include out of body experiences, feelings of transitioning to another world and of inner peace, many of which are also reported by users taking DMT.

The team found that all volunteers scored above a given threshold for determining an NDE, showing that DMT could indeed mimic actual near death experiences and to a comparable intensity as those who have actually had an NDE.

Researchers at the New York University Grossman School of Medicine studied 567 people who received CPR following a cardiac arrest during hospitalization between May 2017 and March 2020 in the United States and the United Kingdom. In the less than 10 percent of survivors, one in five reported the lucid heightened experience.

Lead investigator Dr. Sam Parnia told Newsweek that people have reported a lucid heightened experience while near death in the past, but evidence hadn't been discovered to connect the consciousness with death. The study changes that and shows the experiences are different from hallucinations.

"There have been a lot of interesting reports of people having lucid heightened consciousness as they approach death, but there's not enough research understanding of death from the medical perspective," said Parnia, an intensive care physician and associate professor in the Department of Medicine at NYU Langone Health. "The question was 'Can we find evidence of this lucid heightened consciousness with death and what are human experiences like?'"

Many patients recalled that while the resuscitation was happening, there was a "perception of separating," in which the patient had a visual awareness of the medical team administering CPR. Parnia said these people also recognized that they had died during this experience. People also experienced a perception of traveling to a destination that felt like home, or somewhere they belonged that drew them in, according to Parnia.

The study, which was internally and independently peer-reviewed, found those who survived resuscitation and recalled a lucid heightened experience returned to regular consciousness and came equipped with a higher purpose.

"They recognize the importance of their jobs or having families or whatever it is we do at different stages of our life, but they're not losing perspective of our humanity," Parnia said. "[They] forget the perspective of that until they had this experience, and then the perspective becomes real for them."

It has been clear for some time that some cells activate either initiator or executioner caspases as part of normal development, without causing cell death (recently reviewed in [16]). In some cases, the caspase activities are localized to particular compartments in the cell and result in partial cellular destruction. An example of this type of non-apoptotic caspase function occurs in sperm maturation, dendrite remodeling, and nuclear destruction in mature lens fiber epithelial cells and red blood cells. What these examples have in common with anastasis is sublethal activation of caspases and survival of the cell. What is different is that the cells are not at risk of dying. In anastasis, cells experience a stress capable of killing them if it persists long enough, whereas in cells in which caspase activity performs a normal function, the activity level and/or localization are restricted so as to prevent death. The mechanisms that restrict caspase activity are not yet fully understood.

No. Cells can recover from a variety of near-death experiences. A process called resuscitation was recently discovered, which refers to the recovery from near death in cells undergoing necroptosis [21]. Even the dramatic form of cell death known as entosis, in which one cell swallows another alive, turns out to be reversible [22]: the internalized cell can emerge to live again. 041b061a72
