Poltergeist

A Poltergeist is a paranormal ghost/spirit which is able to manifest itself visually and/or by moving/affecting objects around them.

Poltergeists typically manifest due to a violent or traumatic death or pre-death experience, during their human existence.

They retain their human personalities and in the case of a violent/traumatic experience in life, often exhibit the need for the closure of this event, which if satisfied can release the poltergeist from its state.
