The closest I've come since is involuntary obsessions with playing video games in my dreams. Not something I'd ever want to seed. Quite the opposite, in fact.
generally they don't work out.
In the 90s I was obsessed with Tetris, and actually found new strategies while dreaming. It is such a simple game that the dreams weren't unrealistic, contrary to other dream epiphanies that turned out to be gibberish to the awakened mind.
It was a completely random series of notes.
Here's the pearl of wisdom I captured for posterity:
"Emotions — it's emotions that invented and fricasseed the invisible ravioli."
(I still have the card.)
I made noises with my mouth, and it still sounded cool. Instead of recording those noises into any recording on my phone, I went back to sleep and couldn’t remember it the next morning :(

I wonder if I did compose them, or did I just have a memory of having composed a great song?
What is experience, if not our very latest memory, right?
I wish it would happen more often, that's only happened for one other song of mine. Most of the rest are a lot of gritted teeth and frustration.
On Saturday I already had some ideas for most problems, but there was one that I didn't knew how to approach and stayed a bit late thinking about it.
On Sunday morning I woke up really exited as I solved the damn problem. I immediately knew that probably like dreams, the memory was fragile, so I rushed to my desk to write the sketch for the idea, which after grabbing coffee turned into my solution to it.
There's no way I didn't spent my sleep thinking about it and solving it, likely around the last sleep cycle when I woke up.
There's research out there that supports dreams as places we process emotions. I wouldn't be surprised if that tied in to other kinds of problems.
I woke up and indeed I made that mistake. (This was during covid so the exam was done remotely and I still had the paper with the calculations at home).
Then I fell asleep and when I woke up in the morning, I had a very strong feeling that the issue was definitely the memory and I had to move the ram to the set of slots for the other channel. And that was the issue, broken slots.
What's impressive is not that it worked, but that after waking up I had no doubt that was the problem, even though practically I couldn't conciously identify why I was so confident about it.
I had an old MSDOS computer, which had a mouse, but the mouse did not work at all. Perhaps that computer didn't have the drivers or maybe no such thing existed at that time. That computer had DOS games on it. Just that I could not access some of the applications, when their executables were not immediately children of a top level folder, because I didn't know how to expand folders in the tree view pane, without having the mouse to click on the + in front of the folder name.
One day I had a dream of me sitting at the computer (I spent a lot of time playing as a kid). In my dream I was lamenting, that I could open those folders. Suddenly a voice in my head said: "Well, why don't you simply try pressing the + key?"
I woke up and was excited. Immediately I started that computer to try it. And what do you know ... it actually worked!! More games for me to play!
Years later I also found myself often dreaming of chess games and thinking about best moves, only to have the board grow dynamically and somewhere far away a bishop appearing, pinning exactly the piece I needed for my best move ... back to the drawing board. Those chess dreams were actually somewhat exhausting.
I woke up convinced that it was a real bug, went to work the next day, and proved it. It was exactly as I dreamed. I never had access to our internal codebase, but had seen enough of the front-end and what we stored on disk to piece it together in my dream.
While it made me popular with some folks, it was a strange lesson indeed to discover that not everyone was as thrilled to have an up-start from tech support make such a discovery.
Fast forward almost 20 years later and I've never had anything even remotely close happen again.
