Well, all an orb is, is a ball of spiritual energy. Not a specific kind of spirit. I'm not even going to begin to get into how 99% of what is photographed and claimed to be an orb is not. That aside, remember, we are dealing with the spiritual world and they can manifest in ways we can only imagine. I have no problem believing you could see a face in one. I'd believe it more if you said you saw it in real life rather than in a photo. It seems most people see what they want to see in them.
