One strange thing that happened to me is when I had this dream (following some long and deep programming session) where the "reality rules" were very close to the logical spirit of programming. Suddenly if I had to reach a platform that was very high, I could just "imagine and build my own tools" to add new abilities to my being. Very difficult to explain. I could clone objects if needed. I could somehow "loop" things or actions. etc.

As far as I know I did not solve any programming problem with this dream though.
