Just let them be. Not doing you any harm 😁

That's just what houses do. They expand and contract from temperatures, you're moving around in it (causing it to "shift"), and your utilities are running in the background. It's just more noticeable when you're in there alone. As a homeowner, I pay attention to every noise my house makes. I have to make sure one of those noises ain't about to cost me a grip in repairs🤷‍♂️

And why do my dogs peculiarly stare at ‘nothing’ when I’m home alone at night??

you're never alone

Becuase they only have secrets for you. They don't want anyone else to hear.

And why do i suddenly develop the hearing of a dog?

U makin me paranoid🥺
