Many near-death experiences seem astounding, yet they are based on the premise that individuals died, as deemed clinically dead by medical professionals. However, medical science has not agreed on what constitutes actual death in a human being. It is evident that those revived to share their experiences were not truly dead, but merely in an unconscious state. Science has discovered that the human brain and nervous system rely on electrical signals and impulses, requiring a steady supply of blood and oxygen to function. When circulation and respiration are impaired, even briefly, the brain malfunctions, potentially leading to a complete cessation of activity. Some researchers suggest that the strange lights, sensations, and perceptions associated with near-death experiences may result from electrical malfunctions in the brain and nervous system due to the trauma of nearly dying.
