Washington Irving's Saddle

Origins
Washington Irving was a 19th century writer best remembered today for his short stories Rip Van Winkle and The Legend of Sleepy Hollow. He also wrote several biographies and historical books, and served as the American ambassador to Spain from 1842 to 1846.

Effects
After Mr. Irving wrote his famous story, 'The Legend of Sleepy Hollow,' his horse saddle became imbued with the story's energy. One of the more affectionate artifacts, this saddle will 'attach' itself to a person that it likes, usually through touch. The person it attaches to, whenever they find themselves alone, will be haunted by the vision of a headless, caped rider on a black horse barreling towards them, sword drawn and swinging.

These visions haunt the dreams of the affected, until they are completely sleep deprived and (some would say even more) delusional. The only way to break this connection is for the affected to place a lit Jack-o'-Lantern on top of the saddle. The carved pumpkin will eventually be smashed by the saddle, but the visions will end. Until another person comes along and is drawn in by the saddle, that is.
