And interesting dream-discovery is how the chemical structure of benzene was discovered. There are many other examples of this. I have experienced very detailed “working sessions” during my dreams in which I develop comprehensive designs and breakthrough new approaches to problems I work on during the day. I know a lot of other creative people who have similar experiences. Perhaps this could be a new way to solve problems: focus on them intently before going to sleep and perhaps that primes the brain to do background processing on the problem during REM sleep. This is testable. For example, provide a test subject with several problems to solve. Then randomly choose one to focus on as they go to sleep and later test to see if the chosen problem is more likely to be solved correctly, or is solved faster, than the other problems that were not targeted prior to sleep.
