A ghost is defined as the
apparition of a deceased person, frequently similar in appearance to that person, and usually encountered in places she or he frequented, or in association with the person's former belongings. The word "ghost" may also refer to the
spirit or
soul of a deceased person, or to any spirit or
demon. Ghosts are often associated with hauntings, which is, according to the
Parapsychological Association, "the more or less regular occurrence of
paranormal phenomena associated with a particular locality (especially a building) and usually attributed to the activities of a discarnate entity; the phenomena may include
apparitions,
poltergeist disturbances, cold drafts, sounds of footsteps and voices, and various odours."
