The friend of Redditor Madhats19 recently ripped up an old carpet to discover that, lo and behold, her house has a secret basement. This could either be the beginning of a horror film or the start of a great HGTV show.

Luckily, this friend's story fits more in line with some solid HGTV programming than a gory flick, as what she found inside the cellar was fascinating—and creepy, but mostly fascinating.
