Near Death Experience
Scientists sometimes pronounce it as a post trauma, a massive uncontrolled illusion of the afterlife. The spiritual community often uses the terms of near death experience and post death experience to describe this phenomena. People, who have been through a near death experience, often describe it as a free fall inside a never-ending tube or a cave. When they "back from the dead", they often experience difficulties to describe exactly what they have gone through. Astral projection aims to achieve a similar experience without any health risks.
