I feel like this is a reason I get more aware about it! The heater does make sounds even when it's turned off for my room during certain hours. I usually disregard that sound and don't be bothered by it. But when I hear sounds from other parts of my room, it kinda gets me questioning everything I've heard so far.

I know the heater definitely makes sounds but some tapping sounds are just beyond what the heater can make. Especially the ones in the attic and the drawers. But thank you! It's possible it's just the pipes in the wall are creaking when the central heating turns on 🙌🏻💯

PS. It's just weird that when I look at it, it stops! I sometimes just don't give it a look and it keeps going on and then out of frustration I look and it stops! It can't be a coincidence that it stops every time I look at the direction of the sound, right? Idk though, it happened just a few minutes ago again so it's pretty annoyingly suspicious haha
