While I do believe there are definately unexplained phenomena, I always have trouble with the whole "orb" evidence...
As a haunter how many times have you tried to photograph a scene and there might be a little dust in the air, what happens???
The flash bounces off the dust particulate in the air and creates an "orb".
I take progress shots to show the wife that I've actually been "working" and I either have to wait for a while for the dust to settle or gets lights so I don't have to use the flash. If not there are too many "orbs" to even be able to see the scene!!
Enities? sure I've seen things and felt things I can't explain, but please let's loose the orbs!
