So this guy rents an apartment....
Discovers a trap door...
Opens it, finds stairs underneath...
Goes exploring, finds a secret passage underneath...
And finds... well, go see for yourself, but I maintain that's either a vampire's crypt or a sacrificial murder room. The soft, freshly disturbed earth is particularly terrifying.
On the one hand, this is incredibly cool, as the renter has just doubled his usable space without increasing his rent at all. And if you're a goth, or a D&D gamer, you have instant ambiance!
On the other hand, I have such a hyperactive imagination that this would scare the living shit out of me. I'd have to, at the minimum, park an anvil on the trapdoor. Even if I don't believe in ghosts and vampires, my subconscious mind likes to entertain the possibilities thereof. And that doesn't even take into account vermin, mold, and other nastiness which might make it's way up... and are you CERTAIN there isn't another way in?
It's very cool, but I don't think I could live there.
