After reading George Ritchie's 1979 book Return From Tomorrow, a psychiatrist's account of his own Near-Death Experience (NDE)... I started to ask patients who had survived a cardiac arrest if they had memories from their period of unconsciousness. Within two years, 12 patients out of 50 survivors of cardiac arrest told me about their NDE. That piqued my scientific curiosity. According to our current medical concepts, it is not possible to experience consciousness during a cardiac arrest. Those patients should have no memories at all! Certain elements of the NDE ... might be of particular interest to psychologists. First, the Out-of-Body Experience, or OBE. People have the feeling that during their NDE they have apparently taken off their body like an old coat, and to their surprise they appear to have retained their own identity with the possibility of perception, emotions, and a very clear consciousness. This out-of-body experience is scientifically important because physicians, nurses and relatives can verify the details of the reported perceptions, and they can also corroborate the precise moment the NDE with OBE occurred. Another common experience [is] the Life Review. During such a life review, one feels connected to the memories, emotions and consciousness of those with whom they have interacted in the past, thereby experiencing the consequences of their own thoughts, words, and actions and more generally, their interconnectedness with others. NDEs are always transformational, often causing profound changes in life-insight, the loss of fear of death, and enhanced intuitive sensitivity (Van Lommel, 2010).
