Happened to me all the time. I fondly remember dreaming of an infinite minesweeper plane where I could effortlessly solve pattern after pattern, forever.

That's when I realized that dreams are a mechanism the brain uses to train itself in a best-effort simulation of recent new challenges. Probably for committing new learnings from conscious understanding roughly analogous to symbolic AI to subconscious pattern matching more similar to ML. Months after I remembered those minesweeper dreams, I was able to multitask any though process that did not involve eyes and hands parallel to the game, in fact I solved my fastest boards when my conscious mind was completely distracted from the game. (and it was an addiction, and I've grown or of it)
