I wrote a blog post regarding sleep learning and the integration of lucid dreaming as a tool to achieve this.

What I was trying to note in my post is that all of the research I have read about sleep learning had to do with the playback of trivial facts while in REM. The emphasis was on rote memorization and the ability of the subjects to regurgitate those facts when awake.
Given the appropriate state of consciousness (lucid dreaming), could we be successful in not just the retention of trivialalities, but maybe we can achieve logic deduction and reasoning?
This is what I was trying to accomplish in the experiment setup I outline above in my article.
