The Never Ending Hallway

"If you're not careful and noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old carpet, the madness of mono yellow, the endless background noise of fluorescent lights and approximately randomly empty rooms to be trapped in. God save you if you if you hear something wandering around nearby, because it sure has heard you." Good luck finding the exit. Or... you can just accept the fact that you will never find one.
