Filmed in the middle of the night on a "nanny cam" in our old house (in late September, 2015), I've kept this quiet (only Paul has previously seen it) until now because I know this kind of thing can freak Rachel out.
A couple of seconds in, you can see an "orb" of some description fly from the top of the screen towards our old TV (on the right).
It appears to hit the TV and ricochet off towards the bottom of the picture.
I'm not saying it's a ghost (it's way more likely to be a dust mote... as they really exist) - but it's easy to see how these things can be construed as "supernatural" by those who want them to be.
So, yes, our old house was probably haunted!
