I recently came across a question regarding N.D.E’s (near death experiences).
“There have been people who die but then get their heart beat shocked back with shock paddles right? Well do these people know what happens when you die or is the mind still temporarily going and it turns out to be like sleep?” – Monko
“It is highly improbable that what these individuals claim to have experienced i.e. “seeing the bright light” or “seeing dead family members” is actually realistic. When a physical body dies, the heart ceases to pump blood to the brain hence the brain ceases to receive oxygen and then literally begins to suffocate. The brain under such duress will function for a while before it completely “dies”; this is one of the reasons that people can be brought back to life by having their heart electrically pumped back into action. While the brain is still “alive” it is under immense duress from the lack of oxygen and is subject to fairly bizarre phenomena; it is known that a lack of oxygen to the brain produces a sense of “transcendence” and that one will see a world of explicit bright light, ask anyone that has been on one of those space shuttle force simulators. After death there is ample evidence to believe that existence of self ceases to be. Consciousness seems to be intrinsically bound to the physical realm through the functioning of the brain, after death the brain will cease functioning and will decay altogether consciousness following suit. There can be no afterlife with out a physical body based on the current evidence and research produced by modern science through fields of psychology, physiology, and neuroscience. In short the brain will continue to run for a while after the heart has ceased pumping blood through the body; much like when you cut off a large electronic item quickly and the electric charge remaining within the component runs the item for a short time before finally running out of electricity and shutting down completely. So the mind still runs for a time after immediate death, however, any claim made by the individual after such an occurrence that they saw the bright lights of heaven or their dead loved ones should be considered the delirious superstition being ascribed to the trauma of a suffocating and dying brain.”
