I think I saw some kind of... I dunno... spirit or demon... or some kind of shadow-being once.

I was doing some training one afternoon about 6ish years ago, I was in an office and there was an instructor telling us about all about job safety, etc... I was zoning out, not really paying attention. It was broad daylight outside. The room I was in had about 6 monitors, and on those monitors it was displaying security camera footage. Mostly the sidewalks, outside traffic.

Out of the corner of my eye I caught some kind of shadow on one of the monitors, but the shadow was moving along the sidewalk very fast, and whats more, it didn't look like a shadow on the ground, it looked like... a ball. A ball of shadow just drifting along the sidewalk like a tumbleweed, very fast. I caught it just out of the corner of my eye and it went off screen. I started looking at all the other screens to see if it popped up, and sure enough, it did pop up on another screen, still traveling down the sidewalk, then it crossed the street, and I could JUST BARELY see a car stop in front of it. The shadow ball lifted up off the ground, went over the car, and then back down onto the street on the other side of the car.

And on the screen I saw the car just sit there for a moment, and then take off. The shadow went completely off screen and I never saw it again.

Now, as with all claims like this, it could have been anything, who the fuck knows. But it was VERY unsettling to see. The light would almost bend around it, wherever it would move, and it was translucent. And whatever it was, that car saw it too, and stopped. Somewhere out there, someone else saw that thing, and I'll never meet them and be able to ask if it was as weird looking as I thought it was.
