You are somewhere you shouldn't be. Find the exit.
Something walks these halls behind you. Looking back only helps it find you.
Keep moving. It hates when you stop.
They say the hum stops five doors down.

You wake up on the damp carpet. The hum is back.
The halls are not the same halls.
The door closes behind you. Another hallway. Of course.
Grass. Wind. A sun coming up like nothing happened.
Behind you the door is just a door, standing in a field, and it isn't humming anymore.
