Dude, this happened to me too once... not exactly the same tho. I was a kid and I woke up. I saw the door to get out of the bedroom but always when I got in there it turned into an elevator and it fell down and I woke up in the bed again. I tried and tried and tried again and again and again to escape the dream as I think I knew I was dreaming at that point and controlled most stuff. I think I dreamed stuff like this just in other places more often. I think this is rare but normal.
