He said: “The changes in feeling include a sense of peace and well-being, feelings of joy, a sense of oneness or cosmic unity, an encounter with what seems to be a loving, warm being of light.
“The apparently paranormal features include extraordinary sensory vividness.
“People report seeing colours they have never seen on Earth, hearing sounds they have never hear before, having what seem to be a frank extrasensory perception of things going on elsewhere, visions of the future and a sense of leaving the physical body.”
Professor Greyson also said many NDEs induce a sense of “otherworldly features”.
These otherworldly features include feeling transported to another unearthly or mystical realm.
