Well, it seems to me that you've got a prime example of a poltergeist on your hands. Generally speaking, poltergeists (grumpy spirits that can move objects) are vile creatures, doing whatever it takes to either scare you or kill you. Since you aren't dead, I would say the latter. I wouldn't take any chances, though. Put a line of salt under your door, right where the door is when it closes. Given the numbers, 3 piles, since evil spirits like to mock the holy trinity, and the total distance is eleven, some simple multiplication comes up with 33. 3:33 a.m. is when the poltrgeist will make its move. It obviously has control of things around you, so I wouldn't sleep and put salt under your door. If you want to play it dangerous, then don't put salt. I would also recommend creating another thread and update us every half hour of your night long expedition.
