Usually if I have a problem I can have some nightmare of going through the same futile steps of solving the problem.  Next day, I&#x27;m pretty much ready to try some different approach.<p>Before I sleep I pull out a notebook and scribble down ideas of what things to do and such - there I might come up with an idea to use later on.  Usually some problem and possible solutions.  Sometime at that phase I think of some novel approach to solve some other problem.<p>I find a lot of the aha moments in my dream only sound great while in the dream.  Mainly scientifically impossible in real life...
