5. The Ridges
Initially, it was known as the Athens Lunatic Asylum. Here, multiple lobotomies were performed and the experts there asserted that masturbation and epilepsy caused insanity in patients. According to the British Society for Psychical Research, Athens, Ohio, is listed as the 13th most haunted place in the world.
It is also believed that a 54 year old female patient who ran away was missing for 6 weeks was found dead in an unused ward. According to grapevine, she had taken off all of her garments, folded them neatly and lay down on the cold concrete where she eventually died. Through a combination of decomposition and direct contact with the sun, her corpse left a enduring stain on the floor, which is still visible today. It is said that her spirit now haunts the abandoned ward, till today nobody wants to visit this one of the scariest places on earth.
