Hi busaiku:
Really cute child there. As far as he "orb" goes, I think it's probably a dustie. It can appear large if it's close to the lens and the flash could cause what little illumination is there. I cropped and looked closely, adjusting the contrast, and I can't see that it's illuminating on it's own. Here's a close-up:
Here's an example of an orb illuminating on it's own:
As far as the "ecto" or "ribbon" in the closet, if there was nothing there to cause such a relfection, it could very well be paranormal. Here's a closeup if others want a better look.
I'm not saying the orb is defintely not paranormal, especially if the object in the closet is PN. With orbs, it's a tough call, and who really knows for sure. Thank you for sharing this pic. I was also wondering if you've had any other strange or paranormal activity there. I also believe that we all have our guardian angels or spirit guides, so it's not impossible that's what it is.
Hugs,
Pate
