a spirit or the soul of a deceased person or animal that can manifest itself or haunt the living. Folklore has it that they can range from being barely perceptible wispy shapes to vivid, lifelike figures. Seances, sometimes known as necromancy or spiritism, are attempts made with the intention of making contact with the deceased's spirit. Aspect, phantom, poltergeist, specter, spirit, spook, wraith and demon are all terms used to describe it.
