Ghost Shadow Picture

Tina Haney sent this picture of what could be a ghost shadow...a shadow of her dad sitting in his chair?

"I took it at my dad's house and when I took it, there was no one sitting in front of me. In the picture, you can see a shadow sitting down, but I took the picture of the wall. Before my dad passed away, his favorite chair was in the spot that I took the picture; my mom moved it shortly after he died. I hope you like it - it kinda' gave me the creeps when I first looked at it."
