Frequently occuring in horror and fantasy tales, ghosts generally appear as the spirit of a dead person. Often these will have died in a violent manner or with "unfinished business". Their appearance can vary wildly from tale to tale, from appearing as they did in life through wispy and insubstantial appearances to being generally invisible.
Ghosts are generally limited to the place of their death or attached to a given object or building. Occasionally a main character in a horror or fantasy tale, they are more commonly a plot point who may communicate some information to the main protaganist either directly or by their presence itself.
