Do we really believe all orbs are dust or bugs? When and how do we know the difference?

I believe true orbs are the really bright ones that emit their own light and energy.

Did you see my photos? and do you believe that you can see faces in orbs? On some sites, one dares not even mention orbs.

Yes, I did see your photos, and yes, I think you can see faces in orbs. During an investigation here at my house a man took a photo and got a bright orb in the laundry room. When you did a close up of it, it had a skull in it. I've also taken a photo and gotten an orb that is reddish orange in color, but I can plainly see my dad's face in it. I love this one picture of mt dad. He died on the front porch.
I know a lot of sites darn near ban you if you mention orbs. I don't know what their hang up is.
