In the movie A ghost townRicky Gervais’ character found out that he had temporarily died during a routine procedure – and the hospital staff didn’t tell him about it. She encounters her surgeon, played by Kristen Wiig:
Wiig: “Everybody’s gonna die.”
Gervais: “Yes, but usually at the end of his life and only once…”
Most of us think of death as a one-time deal. Yet millions of people report getting surprisingly close. in a.d questionnaire Prevalence in 35 countries near death experiences (NDEs) which is 10%.
What happens in moments of death?
One of the surprising discoveries is that the brain doesn’t just shut down when we expire. A study of comatose patients who died showed a cascade of activity in different areas of the brain.
Researchers are working on adapting them nervous what informs a person’s feelings and thoughts changes. Of course, they can’t do that with people who “didn’t fly back.”
But some take it back.
What do people report from NDEs?
Many studies show common themes, including a peaceful feelinga a bright light, an encounter with another being, clear thinking, a dark place, a sense of altered time and coming back to life.
Here is an example of a prototype memory:
I left my body and I saw people in scrubs working on me. Then I floated towards the bright light. I met my grandmother. I’m thinking, “I’m dead. This is great!” Someone said I had to go back and suddenly I was in the hospital.
The good news: Many people report pleasant feelings
Most NDE descriptions imply a happy ending.
Researchers in France and Belgium found that feelings of peace prevailed in the experiment. Many reported that they suddenly understood and felt joy.
in a.d multi-site study According to heart attack survivors, some patients feel very calm and loving while receiving CPR.
These findings suggest that the soundtrack to our final performance should sound more like Louis Armstrong’s What a wonderful world than the Rolling Stones Paint it black.
The not so good news is that for some, a near death experience is a bad trip. In one sample14% remembered sad features.
A new theory: the dying dream hypothesis
The striking similarities in NDE memories have inspired scientists to consider biological explanations. Can we relate changes in brain activity to people’s NDE reports?
Plausible theories have been promulgated – e.g NEPTUNE model (A Neurophysiological Evolutionary Psychological Theory of Understanding Near-Death Experience).
But recently a new theory has emerged. It builds on previous models, but adds a few interesting claims.
according to the dream hypothesis of the moment of death proposed by Tapea movie that plays near the end of life can best be explained as a dream-like state created by our brains.
The chain of events begins when the brain is deprived of oxygen, such as during a cardiac arrest. This is followed by an increase in gamma waves and a surge of feel-good neurotransmitters, including serotonin.
At some point, input from the outside world—our eyes, ears, etc.—is cut off, and the brain only produces thoughts and feelings from within. Our life memories fade away.
But they were not chosen at random. Instead, it is the history of an individual’s emotional life defines the tone of the image is soothing scenes or a horror show. Someone endured trauma or unresolved guilt Near death may experience sad, even hellish thoughts. A person with safe attachments and a love history can expect a happy state.
Cultural and religious background also shapes NDE narratives. For example, in Christian cultures a bright light is seen as a being of light, but in Japan it is an inanimate object – perhaps just a bright light.
Many elements of this new NDE theory have played leading roles in previous models, including gamma waves, cascading brain activity, memory activation, cultural influencesand similarities between dreaming and NDE.
Essential Readings on Near-Death Experiences
Fact-checking: Does the evidence support the new theory?
Many of the mechanisms proposed in the near-death dream hypothesis are indeed evidence-based. Older, established theories have also incorporated these robust scientific findings. For example, EEG studies of near-death patients have shown brain activity patterns observed in memory retrieval.
But some of the claims in the near-death dream hypothesis remain speculative.
The biggest unanswered question involves the driving force behind a person’s basic emotional history.
According to this theory, a person’s accumulated emotional past, such as having a life marked by love or moral guilt—defines whether the end-of-life experience is pleasant or hellish.
Visions of Heaven or Hell? This, to put it mildly, seems to be an effect that interests many. Is there any evidence to support this?
No. Although this idea is interesting, it has not been tested.
In short, the new theory brings together scholarship from different fields. However, the newly proposed components still await empirical testing.
What to expect when it expires
So, what do you experience in an NDE (and perhaps when the lights go off permanently)?
Well, it might be nothing at all. less than 40% report that people have any kind of conscious experience. A A study of ICU patients set the number even lower, 15%.
If you have an NDE, you will likely experience feelings of peace, love, and understanding. Hang on. Will our final moments sound like an Elvis Costello song?
I think this is the best way to go out.
