Why do many people who have experienced clinical death talk about the astral exit from the body?
Why do most of them see some kind of tunnel?
What kind of pleasant music and light comes from afar?
People who have experienced clinical death speak about the same sensations. But experts in the field of neurophysiology explain this only by the peculiarities of the brain of a dying person.
Heart failure
Scientists are convinced that after the heart stops functioning, the nerve cells in the brain continue to work for some time.

The final death is set only after the last electrical impulse of the brain disappears. At this moment, oxygen ceases to enter the brain along with the blood, neural activity stops: irreversible changes begin.
Clinical death
Research has shown that there is increased neuronal activity in the brain before death occurs before finally freezing.
Approximately the same can be seen in a person who is conscious. This can explain the strange mystical experience that people who find themselves in a state of clinical death are experiencing. Due to the lack of oxygen, neurons cannot work as usual: they are depolarized.
Death and psychedelic experiences
This experiment was carried out under the supervision of scientists. The patients were divided into 2 groups: one was given a placebo, the other was given a powerful psychedelic.
The second group, who received the drug, said that their feelings were similar to people who experienced clinical death. They felt:
- floating feeling
- a sense of body dissolution
- auditory hallucinations
Living corpse syndrome
And this is found in medicine. So colloquially called Cotard syndrome, when people think that they have already died and are in a posthumous state.
A prime example is a girl who survived an accident. About a week after she woke up in a hospital bed, she thought she was already dead:
The syndrome is explained by a disruption in the functioning of certain areas of the brain, which can occur after TBI or postponed complex infectious diseases.
I see a light at the end of the tunnel
Similar sensations are described not only by people who were on the brink of life and death, but also by aces pilots who are experiencing overload.
At the moment of a very strong overload, pilots are faced with a sharp and strong drop in pressure, against the background of which hypotensive syncope occurs. One of the symptoms that accompanies it is impaired peripheral vision. Pilots who have experienced similar experiences do describe a dark tunnel and the light at the end of it.
Feeling incredible happiness
Firstly, such an effect can be provided by potent drugs that ambulance doctors inject to the patient.
It's also worth remembering that our brains have an opioid-receptor-driven reward system that works at full capacity to numb pain.
Life flashes before your eyes
A number of scientists associate this phenomenon with the activation of the medial zone of the brain. It is she who is responsible for storing the most vivid memories - from early childhood and adulthood. This area of the brain is very sensitive to lack of oxygen, which is why such experiences are so vivid and frequent.
Ghosts, dead relatives, monsters
Scientists conducted a study of the testimony of more than 50 patients who said that at the time of clinical death, they met with relatives or saw / are still seeing the souls of the dead.
The whole group was the same in one symptom - they were prone to sleep paralysis. This extremely unpleasant condition is characterized by temporary immobility and terrible hallucinations. In addition, researchers are inclined to believe that such visions may be either a consequence of trauma suffered, or - a developing disease of the brain or nervous system.
Life after death
It is up to you to believe that such an experience is due solely to brain activity or that our soul falls into some other dimension.
