Ah, but that's assuming you'd have enough time to reach it. It doesn't take long for someone to get you if they're a mere few feet from you. Putting something in the way at least might hinder their movement, but I guess it depends what you sleep with, I think my covers altogether would have enough weight to at least slow 'em. And I keep a hunting knife by my bed, sometimes under my pillow. I'd have something to use if I needed to. lol
