Shadow Man

Photo shows images caught on camera from within my home this shadow appeared as I stay 3/up I could see nothing that could cast this image, after watching this image for a few moments I then took some photo shots of it....If it was just a normal shadow I would'nt be able to see through this, but this shadow you can. Is this a shadow person? I dont know however it appeared while I was working on a clients recording...strange. What are your thoughts on these photo..... click on photos to enlarge.
