I literally thought the same thing last week. Could this be the physical manifestation of the demonic, after I burned my Ouija Board, is when all my problems started( other things caused it, but the TIMING). Sometimes I think I can see them when I look in the mirror, its very creepy, and you may not be so far fetched a s you think. Glad to know that i am not crazy in my thought process, and hopefully we can get rid of these nasty, horrible soul-sucking things. I, for one, would very much like my life back.
