A haunted house is a place where supernatural entities such as PHANTASMS, GHOSTS, spirits, and skeletons are said to reside. PHANTASMS are apparitions or visions of the dead that appear in physical form. GHOSTS are the souls of the dead that linger in the physical world. Spirits are incorporeal entities that can interact with the living. Skeletons are the bones of the dead that remain after the flesh has decayed. All of these entities are believed to inhabit haunted houses.
