Why don’t ghosts fall through the floor if they can walk through walls and glide downstairs?

Good question! Ghosts, like all solid objects, need to be touching something in order to remain standing. Therefore, if a ghost is standing on an empty area of the floor, it won’t be able to remain standing and will appear to “fall through” the floor. They can walk through walls or glide down stairs, however, because they are able to move from one object to another without needing physical contact. In fact, ghosts are so able to move around unseen that they can even “pass through” solid matter!
