Last night I got a somewhat late bedtime to begin with, certainly for a weeknight. So it was a little annoying that after I went to bed and relaxed just about enough to go to sleep, there was this noise keeping me up. Hard to describe, somewhere between a hum and rustling. Except soon I realized something: It wasn't keeping me up exactly. I was somewhere between wakefulness and sleep.
A hypnagogic state, that is.
The sound could have been entirely within my head or it could have been hypersensitivity to the fridge humming. Either way, I woke myself up and it stopped. So then I could actually get to sleep.
It's kind of an unsettling experience. yes. But it's also kind of cool. I was fortunate in not undergoing anything potentially traumatic like sleep paralysis. Hypnagogia complements my writerly side as well.
