Poltergeist
A
poltergeist (German for
noisy ghost) is an invisible entity (
ghost) that moves (and throws) 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.
