I keep meaning to test this experiment, but I never think to grab a spoon when I'm tired. Still, I love the final thoughts that materialize before sleep, which are slightly more concrete than dreams (and thus more receptive to conscious manipulation) but share dreams' liberating illogic. It's possible that none of these thoughts are especially coherent; my vague memories of them have more to do with their flow than their content. And sharing enough bedrooms over the years has taught me that what a person considers astute when he's falling asleep might strike him as gibberish when he's fully awake—statements like "No, you're my lion," to quote my first college roommate.
In his song "Eid Ma Clack Shaw," Bill Callahan wittily describes the disappointment of realizing your half-conscious profundity was nothing more than a stream of nonsense. Let's hope that few people leaving this week's "Idea Talks" experience similar revelations.
