The Box - Dream

I wake up and I am in an 8'x8' room but there are no windows or doors. In the ceiling are 4 small holes (one in each corner) and in the very center of the ceiling is a globe style light fixture. The walls and ceiling are a light grey. There is nothing on the walls anywhere in the room, no switches, vents or anything. The floor is a charcoal grey cork but there are no seams, not even where it meets the walls. The song I Want To Marry A Lighthouse Keeper is being piped into the room but I can not tell from what direction. There is nothing but me in the room and just as panic starts to set in I wake up.
