well what ur talking about semtex is similar to lucid dreaming. when u have a big thing that is getting at u like needing a solution (i presume u mean programming) then i know from experience that your brain will be full of subsoncious thoughts on this topic, since its all a logical step procedure. the brain will go thru possibilities while you sleep. in the morning u can sometimes remember what has happened and provided that u can remember it well enough u can sometimes get that into the program before u forget it!!!
i think programmers especially this happens to because it all has to come from your mind and your mind continues to try to process solutions, neurons firing like a war as they bring up bits of code for you to remember! such concentration means that its hard for the brain to then quickly shut down afterwards.
that i think is prettymuch what is happening.
steven11, u know i have often thought of mu whole body being a machine u know! often the brain is the computer... but sometimes it crashes on me and so i have to spend all day trying to recover it... but thats usually aftera BIG night out!!!!
