Poltergeist

The Poltergeist is a form of ghost whose name means “noisy ghost” in German. They make their presence known by moving things, breaking things, and even interacting physically with the living. Often they are defined as ghosts that cause mischief, sometimes unexplainable noises. They are sometimes believed in modern days to not be actual creatures, but examples of a phenomenon called RSPK, meaning Recurrent Spontaneous Psychokinesis.
