DEFINE: GHOST

Ghosts are the supposed apparitions of the dead.

A ghost is often thought to be the spirit or soul of a person who has remained on Earth after death.

Every culture in the world carries stories about ghosts, but its beliefs vary substantially across time and place, with disagreements both as to what ghosts are and whether such things exist in reality.

(Encyclopaedia Wikipedia)

"Many people become very frightened when they see a ghost but there is in reality no cause for alarm. The real people, their spirit selves, have moved on long ago into the worlds of the afterlife.."
