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.

You’re constantly sweating. Even if your not hot or can’t tell, it’s happening. The sweat evaporates instantly.

That evaporated sweat becomes water vapor in the air.

The glass is much cooler than your body and the air around your body. The water vapor in the air cools down and condenses on the glass, which you see as fog.
