According to Wikipedia[1], spirit possession is a paranormal or supernatural event in which it is said that spirits, gods, demons, animas, extraterrestrials, or other disincarnate or extraterrestrial entities take control of a human body, resulting in noticeable changes in health and behaviour. The term can also describe a similar action of taking residence in an inanimate object, possibly giving it animation.
