Poltergeist

A poltergeist (German for noisy ghost) is an invisible entity that moves objects and causes electrical malfunctions by telekinesis. Doing so classifies them as (inter)active spirits, in contrast to non-interactive ones which engage only in minimal action such as showing themselves. Poltergeister (German plural) are mischievous beings, and connected to an object (usually a building) or a person. The haunting[?] by a poltergeist is called infestation. Most classic poltergeist stories and (presumably) incidents originate in England.

Famous (said-to-be) poltergeist infestations :

• The demon drummer of Tedworth (17th century)
• The Borley Rectory phenomena[?] (20th century)

Both the word and the concept poltergeist became famous by the Poltergeist movies and the TV series Poltergeist - The Legacy[?].
