Cases when people who were near death talked about the “light at the end of the tunnel” and unusual experiences have been known since ancient times. Today, similar experiences describe 10% of cardiac arrest survivors. However, it is customary in the medical community to ignore such “near-death experiences,” mistaking them for self-deception and “mind games.” But after some patients reported things that were impossible to ignore, psychiatrist Bruce Grayson began his own research. He approached the problem from a purely scientific point of view and now, in his book, he shares the results of forty years of research and tells how they turned his worldview upside down. What if death is the border between different forms of existence of consciousness, not the end, but a way to move to a new level? This book forces us to discard stereotypes, introduces the stories of people who have experienced death, and leads us to rethink the nature of death and life and the assumption of immortality consciousness.
