Third Eye Realm

this was taken at the west virginia state penitentiary, the lady said she saw the figure and thought someone was in the prison (no one used it) she didnt know if it was someone from a gang or bum that had taken residence in the jail. something had told her to back up, but she decided to take a picture of it, so she went to the end of the hall and snapped that shot. it has been proven that even with all the advances of science, that they could no duplicate the same shadow and precision of the figure. what do u think it was? a spirit walking the lonely halls of a abondonded prison or someone pulling a prank?
