I have solved various unsolvable issues in a dream.

And I actually remember one solution because I constructed a mental model so I would remember the unique groundbreaking solution I have just invented.

Thus I now remember a ball with curved arrows coming in and out, but I do not understand what it means and what problem it solves.

the sun with its magnetic force lines?

More abstract than that and at software level. For example "hyper-meta-recursion" of functions or DNA-strings. Or neural net as a ball, where wayward thoughts lose their momentum. Or maybe dynamics of self-reflection and consciousness of such a ball... Also anti-gravity is one of problems I have definitively solved, but do not remember the solution right now.
