Seeing Ghosts, Salem - detail

I shot this piece quickly while at a stop light in Salem.
Later when I put the collage together I noticed a dog/creature outside the fence to the right of the woman walking her dog. It does not appear that the woman is aware of this "apparition" on her right, but the woman's dog is moving away. hmmm? am I seeing things?

Note: I did not edit this digital capture.
