Putting my hand NEAR the window makes it all misty.

Question

Putting my bare hand near the window, not touching it, makes it go all misty, why is this. It’s only at the top of the window, the window is closed, and it’s not cold in here. I’ve never seen this before and it’s. a bit creepy.
There’s a video linked below to help.
