I have been following the orb debate
and have found that most orbs are camera artifacts, dust, snow, or rain. But no one ever gets a photo of real spirit lights -- that is what I was told they were many years ago -- that glow on their own. I have seen the lights a few times long ago, but now after my mother-in-law passed away, I have seen a blue glowing "orb" / light coming out of where we keep her ashes urn. My wife has seen it here and my sister-in-law has seen the same thing at her house, too.
It is small and bright, moves around as if it knows not to bump into things, and sometimes goes out the window, maybe to my sister-in-law's house.
A few months ago, I was at a local haunted building taking pictures and saw the same sort of thing and got a photo [above] of it before it got away. I was stunned to see that I have finally captured one.
