I was up early reading Dreamland: Adventures in the Strange Science of Sleep, and I was reading the chapter entitled "Sleep On It," which detailed the research on how our brain often solves problems creatively while we are sleeping . . . there were anecdotes about Jack Nicklaus realizing his grip was off in his sleep, Albert Szent-Gyorgi figuring out how to isolate vitamin C in a dream, August Kekule dreaming of a snake with its tail in its mouth and relating this to the structure of benzene, Paul McCartney waking in a girlfriend's bed with the entire melody of "Yesterday" in his head, and -- of course -- Samuel Taylor Coleridge rising from an opium induced nap with the poem "Kubla Khan" in his brain (though he was interrupted by a visitor while he was transcribing his masterpiece and forgot the ending) and just as I finished this chapter-- coincidentally (or miraculously . . . that's for you to decide) my son Ian stumbled down the stairs, half-asleep, and mumbled: "I had an awesome dream . . . I have an idea for art" and he grabbed a piece of paper and drew a many-headed hydra-like beast, and he did this even before he went to the bathroom, the urge to draw what he had just seen was so strong . . . and the moral is, of course, if you need a good idea, take a nap.
