I believed this strategy when I was a kid to think about a problem before you go to sleep and while you sleep your brain will figure it out for you. You’ll wake up with the problem solved. I believed it just like I believed countless other unverified truths. I think it caused me a lot of sleep problems over the years because I’d be mentally grinding away in the dark, trying to prep my brain for all the wonderful problem solving it was going to do, and… ending up never going to sleep because I had worries, ideas, things to do. I now work hard on meditation-style “make your mind blank” effort at sleep time. Any worry I have, it can be handled tomorrow. (But I have to in good faith have a plan to address it in the morning.) This has made it much easier to fall asleep.
