Almost every tenth person who experienced a near-death state claimed that he/she had been accompanied by unusual sensations and experienced the afterlife. Basically, such people talked about leaving the body and visualization of bright lights.
Afterlife from the point of science
Scientists from the University of Belgium examined the narratives of around 150 patients who survived clinical death. Most patients experienced three sensations: peace, movement through the tunnel, and the light at its end. There were also people who claimed body-leaving experiences.
Researchers also faced an interesting situation. In most patients, the order of sensations was different. That is, only 1/4 of them first left the body, and then sailed through the tunnel. Scientists are inclined to believe that each person will have his/her own dying scenario. It is also possible that the near-death experience may be the same for people of a certain culture.
For 4 years, American scientists had been researching people who experienced clinical death after a heart attack. Researchers talked to both patients and medical staff who were trying to bring them back to life.

After examining all the data, scientists came to an interesting conclusion. Most people could accurately convey the conversations of doctors during the rescue procedure. A third of respondents said that time seemed to start flowing more slowly or even stop. Many people claimed that they had experienced a sense of peace and visualization of bright lights.
These data may suggest that after death, the brain continues to work.
Canadian researchers decided to support the study of American colleagues and examined the brains of patients who were disconnected from the life support device. The study showed that the brain continued to work when the body did not show any signs of life. There was no reaction to light, palpitations, and so on.
According to scientists, the brain does not die after heart failure, but rather begins to work faster and faster. This is accompanied by the release of a huge amount of dopamine, the hormone of happiness and pleasure. It leads to the feelings that dying people experience: peace and tranquility.
In addition to dopamine, the release of the hormone serotonin increases. Because of it, auditory and visual hallucinations occur. Just at that moment, the deceased see both angels and spirits and dead relatives.
Researchers from Israel explained the moment before a person loses a life. At the time of death, the heart stops pumping blood and supplying the brain with oxygen. Because of this, the brain experiences oxygen starvation. The moment with “life flashes before the eyes” arises due to the activity of the prefrontal and parietal lobes of the brain, which are enriched with blood and oxygen for the longest time.
