So like, you know when you're trying to sleep, but for some reason you breathe in and feel all this freezing cold air on your face, even though your room is actually warm?

It's so weird, and this happens about four times a week. There's also no vents near my bed too.

When I get this cold air in my face, I can move over a foot or two, and the air will feel like normal! I also get a feeling I'm being watched too.
When I breathe in this air, it feels like I'm breathing in air on a cold winter day.

I also do not get this freezing cold air in my face only during the night. It happens in the day too.
So far, this has happened in the light blue room, and the mirror room (or yellow room).

Has this happened to you, and if it has, what do you think it is?

I am very puzzled by this, since it only happens to a small part of my room and nothing else is affected by it.
