In folklore, mythology, and modern media such as literary fiction, a ghost (sometimes known as a spectre [British English] or specter [American English], phantom, apparition, spirit, spook, or haunt) is the soul or spirit of a dead person or animal that can appear, in visible form or other manifestation, to the living. Descriptions of the apparition of ghosts vary widely from an invisible presence to translucent or barely visible wispy shapes, to realistic, lifelike visions.
