If you've never laid eyes on the infamous image of Jeff the Killer before, consider yourself lucky. The basic story concerns Jeff, a serial killer who hides in the closet and whispers to its victim, "Go to sleep," before slaughtering everyone in the household. Even more disturbing than his M.O. is his appearance — his face is smooth and stark white, a huge grin and small lid-less eyes. He is one of the most easily recognizable creepypastas, with his eerie stare posted across forums.

His origin story involves a fight that resulted in a chemical burn on his face and caused him to go insane. Soon after, he murdered his family and disappeared into the night to make guest appearances in your nightmares.
