Well, I was previously able to recreate the "path" of how I solved the problem. Recently it has been becoming difficult for me to recreate that path; it is as if like magic that I get solution with me being disconnected from the problem solving process. The feeling is like I become zombie with no awareness when solving a problem and something inside me takes over and does the work. And when the work is done I regain my humanness as if I become conscious again and there is in front of me the solution to the problem, and then I have to start thinking how did I get to this solution?
