While the average person is happy being chased around by angry, three-legged cans of neon-colored soda or falling up a very deep hole on the side of one's head - in his or her dreams, of course - geniuses make good use of their downtime by working on complex problems.
Like the famous six-sided, ring-like structure of the benzene molecule which may or may not have been conceived in Kekule's dream.
Or those beautifully garbled verses in the Beatles' "Sun King" that John Lennon may or may not have "heard" in a dream.
So what did I dream about last night? A supremely awful joke: "Lassidity (rhymes with "acidity") - severe, painful heartburn caused by drinking too much salt lassi."
Waiter, some tissue please. People are shooting jets of lassi out their noses.
