Yeah QD, I did notice that you never actually see all of the moving objects in scenes where that happens. The chair and table legs, the edge of the drawer, you're right about those. Definitely could have just been tugged.

I have trouble doubting these mostly because I don't know how good editing technology is (such as the closing scene "demon girl"). So it's possible that everything else, like the opening clips that look like small, stray clouds, were just added in? How about the girl in the hallway? Was that computer-added or just some actual girl that looked ghastly in the dark?
