Near death.

What is meant by Many people have passed through this stage i.e. have seen death and come back and everyone has had a similar experience. 

Does it really happen? 

If you shut down a Windows computer, the computer goes through a specific sequence of shutting down applications one by one and then shutting down operating system services one by one—the brain is starved of oxygen. If the supply is interrupted, the brain also goes through a process of step-by-step shutdown- Different parts of the brain stop functioning at different times due to lack of oxygen and this sequence is more or less the same in every person who dies, so it should not be surprising that those who die in this process. Experiences are also somewhat common-

Different parts of the brain process different sensations and create different feelings - all of this is combined by the processing of the prefrontal cortex and we get a complete and coherent conscious experience - a part of the brain that is the 'I'. Consciousness creates a sense of presence, a part of that 'I' present in one's bodycreates a sense of being, one part makes different body parts feel like 'parts of my body', one part processes visual signals, one processes hearing, etc. - we now know that The part of the brain that makes us feel like we are in our body is not very efficient andIt can be easily tricked – a slight lack of oxygen supply to this part or intoxication, epilepsy, extreme fatigue, meditation, etc., confuses this part and creates an out-of-body sensation. Seems means we start to feel that we are separate from our body and looking at our bodyThere are - now neuroscientists can very successfully create this experience in the laboratory, meaning that anyone can have an out-of-body experience - so an out-of-body experience when the brain is deprived of blood in the process of death. It is not surprising

The largest part of the brain that processes vision - when the blood supply to this part begins to decrease, neurons start to fire erratically, creating the perception that a point in front is a very bright light - This feeling can also be created in the laboratory, although oxygen is used to create this feelingThis is why it is now considered unethical to do such experiments in the laboratory and such experiments are not allowed - however, from brain scans of animals during the death experiment we can see that their neurons are active the same way. As with seeing an extremely bright light - so do animalsBut we know from experience that immediately before death, the brain releases large amounts of the neurotransmitter dopamine, which creates a feeling of extreme relaxation and happiness—

The parts of the brain that are still functioning are the deepest parts of the brain that have been affected by oxygen deprivation for some time - these are the parts that store childhood memories, childhood cultural training. - These areas are the last to shut down - many neurons in them also fire before shutting downIt seems to cause childhood memories to flash through the mind and it feels like all the stories of the deceased's life have been flashed through the mind in a few moments - but this is all due to the firing of neurons in the dying brain.
