Mental alarm and filters

I set my workday alarm for 9:30 am. Usually I've been waking up way earlier than that and not getting back to sleep, part of my general insomnia. The past two days though, I've woken up at about 9:25. *hmmm* It's not the first time my brain has shown an awareness of when I wanted to get up and anticipated the alarm.

If only it were so good about staying asleep when I want to.

Relatedly, I noticed years ago, on a day when it didn't matter if I slept through the alarm, that even the faint beeping of a wristwatch was sufficient to rouse me. The much louder sound of a garbage truck right outside my window did not wake me, assuming I was still asleep. So there must be a filter: "this faint noise has intention, respond; that loud noise is just environment, ignore."

If only I could activate that filter while awake. Chance of *getting* to sleep while the garbage truck was active, if I was already awake, was zero.

Also relatedly, I've noticed that if I feel tired in the afternoon -- food coma or something -- and lie down for a nap, not too concerned with whether I sleep or not, I'm pretty tolerant of light and noises, and often do fall asleep for a bit. But "going to bed" at night, I'm much more sensitive to little noises and vibrations, and use ear plugs all the time, and often a white noise generation (because, again, MY loud hummy noise is okay, THEIR faint hum or whispering or beat will drive me up the wall.)
