Horror fiction is fiction in any medium intended to scare, unsettle, or horrify the audience. Historically, the cause of the "horror" experience has often been the intrusion of a supernatural element into everyday human experience. Since the 1960s, any work of fiction with a morbid, gruesome, surreal, or exceptionally suspenseful or frightening theme has come to be called "horror". Horror fiction often overlaps science fiction or fantasy, all three categories of which are sometimes placed under the umbrella classification speculative fiction. Haunting is used as a plot device in horror fiction and paranormal-based fiction. Legends about haunted houses have long appeared in literature.
Achievments in horror fiction are recognized by numerous awards. The Horror Writer's Association presents the Bram Stoker Awards for Superior Achievement, named in honour of Bram Stoker, author of the seminal horror work, Dracula. (Wikipedia)
