Backrooms

Opening your eyes after a rather nasty fall, you see acrid yellow walls before your eyes. This seems strange, because you were just in... a clinic. It seems so. You were simply going down the stairs and, through carelessness, missed one. This place was slightly different from where you were before the fall. Rising up on your elbows, you looked around and noticed nothing but yellow walls and parts of a corridor leading to who knows where. Lamps buzzed unpleasantly overhead, and under your arms was a carpet, smelling and stained with something pungent and oily, which was already beginning to soak into the fabric of your clothes.
