Seeing Things Running Through Your Head

I've mentioned that I work at the library now, right?  And I've surely mentioned that it's reputed to be haunted, no?

Well, in case I haven't, I do and it is.

I, however, have not any brushes with the supernatural (unless you count that foul odor that I encountered one evening, but couldn't figure out where it was coming from), though I've talked to a few folks that have (one patron, name o' Roger, said he's never gone up into the attic, because "that's where the ghost is").  I have had plenty of opportunity, in the short time I've worked here, because I'm often alone, and I have walked through the library after hours, when no one else is in the building.  

The closest I have come (other than The Phantom Stench, that is) happened on a Friday night, when I was sitting at my security desk, and I happened to glance at the monitors, which show a bank of twenty images throughout the building.  On one of them was what appeared to be a faceless grey form standing on one of the staircases.  I froze when I saw it, because it looked SO MUCH like a human form, even though I knew there would have to be another explanation.  And then it moved, ever so slightly.

A second later, it turned, and I realized that it was a little girl, wearing a gray winter coat, facing away from the camera, with the hood up over her head.  Once she turned and went back up the stairs, it was clear what I was looking at* . . . but I gotta admit, for a second, I thought it had finally happened to me.

I went back and got a screengrab, so you could share in my brush with The Other Side.  What do you think?

*Also, if you zero in on that particular angle, the details become much clearer that they initially appear in a tiny lo-res rectangle.
