St. Francis Orbs

I love reading about paranormal activity and have had many experiences on my own, although I have never captured anything out of the ordinary on film. This picture was taken by a friend of ours at St. Francis Mission, which is a church but also a place where people go to find recovery from addiction. There are quite a few people who have entered this Mission seeking recovery; not all have made it and it would not be hard to believe that some of them could be hanging around in spirit form. Due to the transparency of the orbs, I tend to think they might simply be dust particles. Recently, I read that orbs tend to be more solid, rather than transparent or containing "faces". I don't know too much about this, though; I am still learning. At any rate, it's an interesting picture. I look forward to taking some of my own, maybe on a digital camera. Because I didn't capture this shot, I don't know if it was taken with a flash or what the light conditions in the room were.
