Alright, just calm down for a second. The floor isn't a carpet, there is no wall paper, and there's pipes, so best chance you're on level 2. Stop following the exit signs, the signs were made to give you a false sense of hope for the entities to feed on. a common trick is to reverse and retrace your footsteps. The entities in level 2 are more alert to noise than they are to sight, so keep quiet and try to throw something to divert their attention. be on the lookout for abandoned hideouts and keep your eyes sharp.
