possessed by demons, & this was sometimes a component of ancient oracles.  In connection with this, it is worth pointing out that a respected modern-day professor of psychology once witnessed a friend, who was suffering from paranoid schizophrenia make a specific & surprising prophecy that turned out to be perfectly accurate.  The professor had no explanation for this event. Although one is tempted to hypothesize that there is a link between altered mental states and psychic ability. 

Some also associate the Ouija board with demoniacal prophesy, & those who have seen Linda Blair in The Exorcist will recall that this was how her character's problems began.
