Caged

I wake up in a cold bare room, that looks like a cell. Four walls, all brick, a concert floor, a little window with three little bars, and one bed, if you could even call it that. Its springs are popping out and its filthy, it looks like it might even have some blood stains on it. I think it might have rained earlier, the room is damp and musky. I attempt to get up but fall right back over, my heads pounding and my body fills with nausea. Im on my knees now my clothes are torn, my hands are scrapped, yet I have no recollection of gaining any of these injuries. How did I get here? Where is here?
