This is cool. I was allowed to look at the original electronic "Negative" so to speak. The light event is just as clear on that. If you zoom in on the original you can see how it has a vapor trail. And its heading upward. If it was heading down I would say it was a rain drop, but that's obviously not possible here.
Whatever it is, its obviously cold enough to create a spontaneous cloud event. Sucking energy out of the atmosphere. I've heard reports like this of rain falling in the opposite direction before, but mostly in the context of in-human hauntings or poltergeist.
