I can hear vibrating sound in my room?

I'm laying in bed and I can quick vibrating sounds and it's freaking me out becsuse I don't know what it is, I've checked all the electronics in my room, it's not my phone because I'm using it now, my iPad is turned off, my laptop is under my bed and has been off for months so can't be that, It can't be my tv or my sky box or tv remote. It's really windy outside and my windows always open but I don't think it's coming outside because it sounds to close and bold, sometimes the vibrating is really loud and I have a small room and it's hard to figure out where it's coming from? It's creepy

I know this sounds so sad but please leave serious answers hahaha
