Be Careful you are not alone.
Backrooms found footages contains some footages recorded by survivors of backrooms.
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 moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in.
God save you if you hear something wandering around nearby, because it sure as hell has heard you.
RUN! as fast you can if you hear something wandering near you.
