Either there’s a creature outside making a faint and intermittent but regular sound….
Or one of my neighbors is snoring so loudly (at just 9pm) that I’m hearing them through the wall…
Or there’s someone breathing in my room, and it isn’t me.
And with that thought, I have officially creeped myself out.
PS It’s probably a frog or something. That’s what I’m going to tell myself and hope that helps me sleep.
