Anyone believe in Ghosts ?

My wife is the only daughter of the seventh daughter of a seventh daughter. Don't know what that means, but she says my dad is living with us and mom pops in for visits from time to time. Dad passed last February and mom passed in July '87. Always thought she was pulling my leg until I got a picture with dad in it. She was posing with the cat and about the time I snapped the picture, the cat swiveled his head upward like he was looking at something on the ceiling. There is a silvery orb in the upper left corner of the picture that the cat is looking directly at, just above and to the left of my wife's shoulder. There is no way this is a reflection from the flash because the background is a white wall. The camera is a Kodak digital, 5 megapixel that has never thrown a reflection from anything yet. After the picture was taken, my wife said, "See you later George". If you like I can try to shrink the picture enough to post. Put me down as a confirmed believer, I've seen too many weird things before this not to believe. Tried to add a link unsuccessfully. Pic is at photobucket search grumpuscreature. It's the only photo there. Wife says the orb is mom and dad both. First really good look she has had at it.
