While plenty of America's abandoned insane asylums offer spooky tours, overnight ghost hunts, and museums filled with the torturous relics of psychiatric history, there's one defunct mental hospital in Ohio that cranks the creepy-factor to 11. Sure, it has all the hallmarks of a great local haunt - rumors of spirits, beautiful decay, and even an adjoining cemetery, but it's what lies hidden on the top floor of the building that truly terrifies visitors: a human-shaped stain where an escaped patient lay dead for over a month.
