(Click Photo to Enlarge) This picture was sent in to us anonymously via email. The sender writes: My sister sent this picture to me and I thought that I would share. There seems to be a mysterious orb in the photo covering my husband's right shoulder. Even stranger, it seems that the dogs see it too - they appear to be staring directly at it. My sister believes that the orb came with the Christmas tree, which belonged to a women that is now deceased. Could this orb be the spiritual presence of the former owner of the Christmas tree, merely wanting to enjoy one last Christmas?
