Dark Mass/Shadow Forms in room and moves off to the side

In Los Angelels, CA. we investigated Angel City Brewery. We placed a static camera in what was once the old wash room where a night watchman died. We capture a shadow that forms in the middle of the room and then moves to the side. It is kinda hard to see, and takes a bit of a trained eye. Watch it a few times, let us know what ya think at ChillSeekers.com
