Sleep does not come easily to me, at least when I’m supposed to be sleeping. (Afternoon naps are much easier.) Here are some mental things I do in place of counting sheep.
- Count primes. Eventually the math of figuring out whether a number is prime puts me to sleep. Or I’ll do something else arithmetic, like a 47 times table.
- Word stuff, e.g., change WOLF to FLOW, or see how many words I can think of that end in -urry. (Slurry, blurry, flurry, curry, hurry, furry, purry…)
- Linguistics puzzles, like phonetic rules for allomorphs of number-related words in Japanese. Not that I have much of a vocabulary to work from, after three months of class.
- Japanese vocabulary review.
- Think about Lunar-related things, like what aspects of the four distinct versions of Lunar 1 would I combine into an ideal game, or how could Genesis/Dragon Song be turned into a game worth playing.
- Knitting (or crochet) planning, either for a possible upcoming project or an existing one such as putting pockets on the giant cozy sweater.
- Math related to knitting. Recently it was figuring out integer values for sides closely approximating a 30-60-90 right triangle. This one actually backfired on me because after doing all these calculations in my head and coming up with a couple of acceptable solutions I had to turn on my phone and find out which was closer.
- Listening to music inside my head. Sometimes I notice things I hadn’t noticed before, which is kind of bizarre.
- Analyzing chord progressions of music I know well. I’m a bit rusty on this though.
- Making up song lyrics about my cats.
