I have no history of mental illness in myself or my family, but my family is kind of superstitious.... My Grandma swears that I am a reincarnate from the Titanic.... When I was barely old enough to talk I would tell stories or people I knew, details of our conversations, what they were wearing names, describe the boat I was on.... many things that were impossible for me to know about or understand at that age, and I did it for years (as she tells me, I don't remember). The details never changed, there were no "flaws" in the stories that made them easy to play off as a child's imagination, it was down right creepy to her. Also, my cousin has "spoken" to our deceased great grandmother" and found out things that were very private and personal about other family members that were impossible to know... I think there are things that happen that are "supernatural" or "spiritual" that are impossible to explain outside of the obvious answer to us... that it is real and can not be explained away by mainstream science....
