As you can see, the foreground action looks like the video is being played at 2x or faster; however, meanwhile, the window shades can be seen lazily blowing in the wind in the background.
You may need to watch this video twice to see you its significance: once with your eye on the faster-than-normal action in the foreground; the second time with your eye on the blinds in the background.
This is also not the first time I've captured on video what looks like demons springing up from the floor [see, for example, VIDEO TIMELINE | Masked Hobgoblin Demon Springs From Floor].
Also, make sure you're viewing the movie at the highest-quality setting; otherwise, you may not even see the blinds move (the wind was blowing only gently).
Update on August 15th, 2014
This was an attack by demons, who knocked me out cold, did something to me in "ether time," and then disappeared. I tried to fight (that's my hand you see flailing into view of the camera); but, of course, it never works [see what demons do to people "in the ether" in PHOTO | Camera in motion reveals demon-possessed (or surgically assaulted) guest].
By the way, this video was made at Little Orchard, while I was in respite care, after having suffered cellulitis, which I picked up at Dave Ayala's apartment, as have so many people, according to a collection of police reports [see police reports].
