Extend the Story - Add a Room

It fits! You push the door open, using a lot of force. It's a heavy door to begin with, and its a little rusted on the hinges, making it stick. When you finally get it open, you see a light fixture hanging from the ceiling. It's off, you think. So you go to turn it on. You hear something behind you, and you jump... You're scared now, and everything is dark. But you set your mind back to thinking logically. You find the cord hanging from the light, and you yank it. Much to your advantage, it turns on. You look around, find nothing. No one, and no items. You're in an empty room, & there is another door. You...

Run right out the door you came in, and keep on running until you get to your vehicle. Where you stay and hope someone finds you.
