What is ghost?

A ghost has been defined as the disembodied spirit or soul of a deceased person, although in popular usage the term refers only to the apparition of such a person. Often described as insubstantial and partly transparent, ghosts are reported to haunt particular locations or people that they were associated with in life or at time of death. A ghost - or spirit or apparition - is thought to be the energy, soul or personality of a person who has died and has somehow gotten stuck between this plane of existence and the next. Most researchers believe that these spirits do not know they are dead. Very often they have died under traumatic, unusual or highly emotional circumstances. Ghosts can be perceived by the living in a number of ways: through sight (apparitions), sound (voices), smell (frangrances and odors), touch.
