Third Person Ghost Picture

Crissy of Centralia, Illinois sent us this intriguing ghost picture. Somehow, a third person seemingly showed up near the bottom of the photograph:

"Me and my sister were in her bedroom all by ourselves taking pictures with her camera phone. I was sitting on the bed when I took this pic! She moved so its kinda' blurry, but at the bottom right below her hand, we see a face. It looks like its trying to duck out of the pic!"

The question is whether it is a face or not, as we see her hand fully formed within the head, as well. Could her hand and something else have formed the head and facial features, or is it a ghost under her hand? You look and decide...
