What are Ghosts?

A ghost is a non-corporeal manifestation of a dead person (or, rarely, an animal or a vehicle). It is often thought to be a manifestation of the spirit or soul of a person which has remained on Earth after death. According to some beliefs, a ghost may be the personality of a person after his or her death, and not directly tied to the soul or spirit. Every culture in the world carries stories about ghosts, though they often disagree as to what ghosts are and whether they are just figments of imagination or a part of reality.
