What Could Be In My Shower: The Grudge

What Could Be In My Shower: The Grudge. Ever since I have watched the movie The Grudge I have been frightened that a little chinese girl or a grim-reaper sort of thing will try to eat me in various places, including the shower. I don't understand why a movie monster would try to eat me when I did nothing to provoke it, but it most certainly will try to eat me for just being around. Most certainly while I'm in the bathroom.
