One of the biggest cliche used in movies is a portrayal of an event that transpire near death. A near-death experience (NDE) is an occurrence triggered by impending death. There are five stages of Near Death Experience: peace, body separation, entering darkness, seeing the light, and entering the light. According to Research, while 60 percent of the people who go through Near Death Experience get to the first stage, only 10% successfully reach the fifth. Often, it involves imaginary entities that will provide company to the person. It is created by the brain as a form of coping mechanism.
There have been numerous research and proposed explanations for Near Death Experience. It was hypothesized in 2010 that the excess CO2 in the bloodstream alters the chemical balance of the brain and tricks it into “seeing things”. Another explanation is the increase of serotonin in the brain triggers NDEs. Another study suggested that brain has the capacity for neurophysiological and neurochemical activities, and can cause internal states of consciousness at near-death.
Is Near Death Experience a mystical tug of war between a mortal and death or simply a phase of chemical reactions in one's dying brain before it shutdown for good? Little by little science is unfolding the mystery.
