Each puzzle was accompanied by a unique sound.  Then, as they slept, they heard the unique sounds of half the brain teasers.  The next morning, the participants were able to solve those puzzles whose sounds they heard while sleeping some 55% more efficiently.   If you have an nagging issue, try associating a tune with it.  Then play the song at low levels as you sleep.  You might just wake up with a brighter idea.   Kristin E.
