Ghost Pictures: Faces On Stones

Deidre took this picture...we think in Germany. Do you see faces on the stones? We see three that all look like women faces to us...but are they ghosts?

"My name is Deidre. A few months back my husband and I went to a cemetery to snap a few pictures. We went in the back part where the very old tombstones are. You couldn't read the dates,names or anything. We we came back I looked through the pictures and found faces on most the tombstones. You can see the one on the far right, it looks like a woman."
