Near Death Experiences can be called many different things. Some call it Kundalini, The Awakening, Cosmic Consciousness, The Opening of the Third Eye, etc.
There are many elements which could induce an NDE. Death, surgery,
hallucinogens, gravity, meditation, seizures, out-of body
experiences, coma, dreams, alien abduction, relaxation, falling, etc.

covered and hidden from eyes that see. So faint their echo. What dance
thus laid this path, I wondered to myself. Was it me in another place
