Orbs - Dust particles or Spirit

My dear friend Jae took this picture during the first Advent weekend. It's the first picture I've seen that contains a spirit orb (or an orb of any kind for that matter). Personally I think this may be my daughter's guardian angel. My daughter is the little girl looking directly at the orb hovering above her.

I Googled orbs to find out more and came across an article on Wikipedia that claimed that orbs are nothing but dust particles, droplets of water or small insects that are out of focus and catching the light. If that were true, I'd have a lot more dust orb pictures from inside my house lol

I do believe that perhaps not every orb picture is a picture of a spirit entity but I have a feeling this one certainly is - in spite of the snow machine blowing soapy 'fake snow' in the background. The reason I believe this so strongly is that the day before the picture was taken, I was able to see orbs with my own eyes against a clear blue sky (this was the day when Uranus went direct in Pisces and the veil between the worlds felt very thin).

Also, Jae managed to capture some orbs in her garden the day after this picture was taken....

I would love to hear from all of you who have experienced orbs. What are your thoughts, feelings, intuitions?

For those of you who would like to know more about the spiritual take on orbs captured with digital cameras, I recommend the book 'Enlightenement through Orbs' by Diana Cooper and Kathy Crosswell. A lot of their insights ring true with me, and they also mention the fact that perhaps not all photos of orbs contain spirit manifestations. We need to use are intuition and ask our angels for guidance...
