Weird things can happen like this when you're sick. Especially if you're taking any medications, or have a fever at all. While your body's trying to fight the illness, your unconscious mind comes up with some wacky images. I've experienced the same thing.

I can't give you any feedback about the possible OBE, because I've never experienced one (and I'm not entirely convinced they even exist). But if you were sick at the time, I'd bet money you were just trippin' out.
