A ghost is a disembodied spirit of a once living person that hasn't made the transition from this world to the next, usually due to an untimely death such as murder, suicide or an accident. Ghosts have been reported all over the world for thousands of years.
The word "ghost" may also refer to the soul of a deceased person, or any spirit or demon. Frequently similar in appearance to that person, the ghost will usually be encountered in places which he or she frequented in life, or in association with the person's former belongings.
Probably the most famous photograph, capturing a ghost on film, of all time was taken by photographers Captain Provand and Indre Shira while shooting for Country Life magazinein 1936. The photograph appears to show a ghost, known as "the Brown Lady", descending a staircase at England's historic Raynham Hall
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 odors."
