Jeff the Killer is one of the most well-known characters from internet horror, or creepypasta. His story tells of a teenage boy who was bullied, attacked, and left disfigured. After a mental break, he burned off his eyelids so he could never stop seeing his reflection… and carved a permanent smile into his face. Jeff disappeared soon after, and strange murders followed. Witnesses claim a pale figure with jet-black hair and a twisted grin told them to “Go to sleep” before vanishing.
