A supernatural phenomenon
itself as a force
that moves objects around, sometimes in a destructive
manner. While some theories identify the poltergeist as a ghost
, others say that it is the unconscious
use of psychokinetic powers
by a resident
of the afflicted house
, often an adolescent
. (Poltergeists do seem to frequently pop up in houses where a teenager
or a child nearing puberty lives.)
Also a 1982 film directed by Tobe Hooper and written by Steven Spielberg in which a suburban family is terrorized by angry ghosts. The lines "Go into the light" and "They're heeere..." are from Poltergeist.
The word comes from the German, roughly translating as "knocking spirit".
