I've noticed some of my pictures have these circles. When I enlarge them they are pretty, like rainbow circles within circles. At first I thought my camera lens had water spots so I cleaned it and cleaned it but they keep showing up at different times. My daughter said, "Their vapors from your breath," but I think that they are too far away in most of the pictures.
Anyway, I forgot about them until I heard Klint talking about "orbs" and about a co-worker that was talking about them, and how there is a lot online about them too. He said, "Just type in 'orb.' No one really knows what they are, or even if they are something. They could just be reflections of dust, raindrops, etc.
I prefer to think that they are angels than any other explanation I've read so far. There are so many of them and I keep thinking of the Bible verse that says - "since we are surrounded by so great a cloud of witnesses..."
Klint had been up on that ladder working on the siding before this picture was taken. While he was up there as he worked the ladder wobbled away from the house threatened to fall over but he caught himself. He got down off the ladder and they were talking about it here. I was just wandering around taking pictures and the picture showed all these busy circles. Maybe they pushed his ladder back to the house, maybe.
My daughter sent me this cartoon which goes right along with this topic.
Here is a link to a person that believes that these unexplained rainbow circles are probably angels. It's something interesting to wonder about.
