I watched a Nova documentary on dreams yesterday. It was about what is the purpose of dreams? Why did Mother Nature make us, and other animals, dream? It had some studies where people were tested on certain skills and then when they slept they were either woken up before dreaming, after REM sleep, or dreaming without REM sleep.
They found that the people who dreamed about the tests improved dramatically more than people who didn't.
I wonder if dreaming of quilting makes a person a better quilter/piecer.
