After researching Near Death Experiences or NDE's I believe that the Soul survives after death and goes to another realm, it usually looks like whatever the person having the NDE believes heaven to be, for some it's like an earthly paradise, for others it's like being in front of Gods throne praising him, the Egyptian's and American Indians have their own and so on, you can also visit other people's heavens or realms, it's quite interesting actually, and you are reunited with your loved ones. Of particular interest are the NDE's of people that were born blind, after being revived they reported having sight, and described what people and things looked like when they floated above their bodies, scientists are baffled about that one.
NDEs are more to do with a uncontrolled release of neurotransmitters in the brain near death than any actual experience of the detached 'soul'. This is borne out by the fact that the people's near death experiences are based on what they believe heaven to be. Obviously not all of the heavens are real, and the experience is simply an interpretation of the flurry of false sensory information manufactured by the excessive neurotransmitters in a way that is consistent with their belief system.
