I have photographed my share of Orbs as well. Some may be dust or water vapors, but some are real.

I experienced something exceptional concerning orbs. I went to a psychic's house and was brought to a stairwell and the doors were shut. Everything was recorded on close circuit, infrared.........I did not have a view as to what was in the stairwell with me, but I will tell you what I saw as it related to other people,

As people sat on the steps in real time, I witnessed bright white orbs zoom past them, and go to them. A couple of orbs I saw tried to materialize into a human shape. I witnessed a widow's head being stroked by a black mass, along with the stroking of her arm. It was the most amazing thing I ever witnessed!

While I was in the stairwell, I could hear the people in the other room witnessing what was occurring to me if anything. I should be receiving the evidence soon along with any evp's which were picked up during the event.

The Psychic is very good, and works with police departments in solving crimes, ect. and is active exposing fraudulent mystics, so she is above board. She is also tested four times per year and is one of only two psychic's who is recognized in the whole state of California as being a true psychic. If you would like to see her website it is: http://www.nancybradley.org/

Anyway, just thought I'd let you know about this as the orbs did display intelligence and tried to materialize by flattening out into a kind of longish and wider shape....which seemed to ripple. Its hard to explain, but some were definately trying to form into human appearance.

I am a skeptic and have been pondering the link between orbs and spirit manifestation for sometime, and I definantely found out that many orbs are spirit or perhaps the spirit is in the orb itself as a kind of spark which can project the covering into a complete materialization if strong enough.
