First of all, I do believe in spirits because there is just too much that we can't explain.

I would try to find out how to tell the difference between dust particles and actual orbs. I know that they are often confused but I have no idea how to tell the difference.

Lastly, I just wanted to say that I think that what you are seeing in your pics really may be Natalie still hanging around. I've said it before but I don't think you have let go of her yet. You have to stop avoiding the pain of losing her and deal with your grief. She's not going to leave you until you've let go. Have your son take a few more pics of you, the results could be interesting.
