Was it a Ghost?

I've been going through hours of video from our Halloween ghost hunt at Owyhee Lanes and Restaurant.  After awhile your eyes start to cross, you think about nodding off and then "Bam" it happens.

This is off the static camera we set up.  It was from a Gopro. We wanted to have a video going that would hopefully catch the women's door to the restroom opening and shutting...something else happened.

In section 3 about 6 minutes and 38 seconds in the Gopro caught this. I put up a few seconds before and after so it's easier to watch.  But basically there was nothing happening before and nothing after, aside from me wanting to take a nap.

Is it a computer program to get your attention, a power surge, or a message from the other side.
