Thanks for the info. 
Fascinating stuff. Before my computer crashed, I used to have a website marked to several ghost webcams, including one of an abandoned hospital. Couple of times, I actually saw stuff on the webcams & was able to report it. Way cool!
That
is way cool!
Reminds me ... in one of the hospitals I worked in, the older building had seen many transformations, one of which was a hospice. A security coworker and I would go up to the abandoned floor and see/hear all kinds of things in the middle of the night. Of course, there were a few legends to go with, and several suicides in some of its incarnations/history. So it was choc-a-bloc with phenomena.
Amazing how cameras can seemingly pick up stuff that our naked eye cannot. Makes me wonder if we are so programmed NOT to see such things that we literally block them from our reality. The camera, of course, has no such prejudices.
Yes, that is fascinating.
For myself, that which I've seen almost always starts in the peripheral vision. It doesn't go away for the frontal view, but direct viewing doesn't seem to initially ferret out the forms. It's a bit like bird-watching .. you train yourself to go "quad-screen" in your vision, to keep the birds unaware/un-threatened by your gaze.
Saw something here just last night, in fact.
