Imagine finding a hidden staircase in your home and then discovering someone has been living in your walls. The story and creepy pictures were posted on reddit.com.

See the hidden bookcase, spiral staircase and mini bedroom, complete with candy wrappers and weird dolls. Be advised, some of the language used to describe the photos is NSFW.

If I found this in the walls of my house, I'd be on the phone with the cops.  How about you?
