That was my first thought too, but since it shows up in different cameras - with different media even - it's a little harder to understand. There was a website once that had tons of pics like this and attempted explain them all, but I haven't a clue how I found it, what it was called or how to find it again. It might have been on one of our Halloween threads here. I'll have to go back and see if I can find it.

I'm not sure I believe in all that spirit stuff, but I'm not sure I don't believe it either. Eerie.
