In college especially before a test my brain was on study mode and would not turn off. Most often I couldn't sleep because I was trying to solve a problem. There was no problem it was just nonsense and no solution. I was going through the motions of it but it was pointless. I wish my brain actually would have worked on actual problems while I slept. edit: I also recall when I was a naive late teen early 20s "song writer" (wannabe) I would often wake up with lyrics. They were also nonsense. Literally. I had a notepad and wrote what I thought was great but it was just gibberish.
