One of the most confusing and misunderstood hauntings is that of a poltergeist. So what is a Poltergeist? A Poltergeist is a supernatural energy supposedly responsible for physical disturbances. Also known to be "recurrent spontaneous psychokinesis" or RSPK - the result of psychic energy generated (usually unconsciously) by a person. This person is usually emotionally disturbed in some fashion, and is somehow the cause of the activity. This person usually is unaware they are the cause of objects moving or doors slamming. Adolescent females are the most common center of this type of activity. The poltergeist haunting is also known to be very difficult to determine and rid.
