I somehow found this when searching for this glass-floored bathroom built on top of a 15-story elevator shaft (http://www.dailymail.co.uk/news/article-2138319/Is-worlds-terrifying-bathroom-Toilet-hangs-15-storey-lift-shaft-luxury-penthouse.html). Somehow. Thanks, internet! (but at least for both of these there are no clowns (http://www.dailymail.co.uk/video/news/video-1094909/Terrifying-clown-prank-make-afraid-dark.html) involved) (and it's ghost-free (https://zombiegames01.wordpress.com/2010/10/19/urban-legends-around-the-world-toilet-ghosts-japan/) ... hopefully)
