Underground Railroad Ghost?

I was taking some promotional pictures for characters in an upcoming independent action film on July 7, 2008 around 5 or 6 pm. While taking the pics in my brother's house I didn't notice anything strange. When I went back to my computer and uploaded the pics and reviewed them, I noticed something strange above my brother's head. None of the other pics showed anything and were all shot in the same area. In the pic the cloud-like object is solid enough to obscure the outline of the ceiling behind it and if you look at it, it kind of looks like a head moving from right to left.

It also looks like hair is flowing behind the head, possibly dreadlocks. I should mention we live in Drexel Hill, PA just outside of Philadelphia, and our area is known for historically being one of the last stops on the Underground Railroad. A couple blocks away, when I was a child, there was a supermarket that was said to have been a "station" back in the day, as well. Since no one ever died in my brother's house (to our knowledge) we think maybe it is the ghost of a runaway slave . . . if it is a ghost at all.

Any ideas are welcome.
