This has happened to me on a few occasions, once during SAT prep in highschool, I woke up with the answer to a hard math question a friend and I had been stuck on. I’ve also dreamt in code after a long week at work - the code was mundane and just a reiteration of what I’d been doing during the week, and didn’t involve any interesting breakthrough solution or anything.
