sounds like sleepy time

I don’t know why, but there’s a certain pitch that makes me sleepy. Dunno if it’s a noise I heard a lot in childhood or whatever, but if something is at this pitch, I have to fight the urge to yawn and curl up and pass out.

I can recreate it in the shower – covering my ears until the sound of the water gets high enough to hit this particular note.

The shop next door is getting renovated and the power tool they’ve been using all day is at just the right pitch.

I’m yawning as I type this o_O
