One of the most handy, readable, informative books about near-death experiences (NDEs) is Jeffrey Long’s Evidence of the Afterlife. In it Long, a radiation oncologist, offers nine lines of evidence for why NDEs are real and not just dreams or hallucinations.
Among those nine lines of evidence, Long considers one of the strongest and most dramatic to be the fact that, during NDEs, blind people can see—including people blind from birth. People with that unfortunate condition do not see even in dreams. They know that vision exists, but can’t imagine what it is—as if someone had told you about some additional, unimaginable sense.
Yet, in NDEs, even blind-from-birth people see—in full, vivid detail. Long calls it “medically inexplicable.”
Probably the best-known case is that of Vicki Umipeg-Noratuk. Her story was first told in a 1998 study of blind people’s NDEs (and OBEs, out-of-body experiences) by Kenneth Ring and Sharon Cooper of the University of Connecticut. Ring, a professor of psychology, and Cooper went on to publish Mindsight, a book based on their study.
