My friend Noah and I, we do this urban exploring thing - old buildings, houses, hospitals, hotels - and film it. It's a niche industry, but it actually pays pretty well for the right production quality and compilation. Like anything else, if you do it often enough, it starts to seep into your subconscious and become part of the landscape. Which is a not-so-short way of saying that isn't entirely unusual on all bases.
Yeah, I got the run-down. Pocket-dimension, weird ass hellscape, something-something ominous.
