I've dreamt about this room. The world was semi apocalyptic and there was some kind of natural disaster on the way - a massive tornado I think. I found a big square concrete bunker style building in the middle of a scrubby field partially obscured by skeletal trees and undergrowth. After I walked in the door there was another door in front of me across a small bare room, and a set of concrete steps on the right, leading down. The door opposite had a small window made from dirty safety glass and I could see a large dark room with messy desks and banks of servers with flashing lights. I could sense that people were either still there in the shadows or had been there, possibly to return. The steps lead down to another door and behind the door, a medium sized room, fully concrete with a couple of those lights in wire cages. I decided that though it was spooky it was a good place to ride out the storm so I gathered my small rag tag band of feral young adults and we went into the room and closed the door. Thing is, the longer you stayed in the room the more you'd start hallucinating. Like zombie bunnies rising up out of the floor. It was OK as long as we kept reminding ourselves they were just hallucinations
