Exit signs

I’m asleep in a large round room. The circular wall consists of dozens of doors, each with a neon ‘exit’ sign above it.

I awake and cry “Oh yes!” as I grab the handle of the door nearest me. I so hate being confined to this place. Bolting through the open door I stumble into the room I just left.

Disappointed and resigned I finally admit to myself that I’m a Möbius strip, a Klein bottle; where every exit door is also my front door.
