Like many other psychic abilities out there, no one is sure why such abilities are in existence, how they work, or why someone has them and another does not. One theory suggests that it’s a genetic transference since most psychic abilities run in the family.
Edgar Cayce states that psychic abilities are results of a soul going through many incarnations.
Another theory suggests that psychic ability may have a connection to people who have gone through a near-death experience (NDE).
The individuals who have returned from death have found a doorway between the physical and spirit realm.
