IOWA CITY, IA—Freshly jolted awake from a peach-tea-induced nap, Sumatra Café patron Laurie Dubar said she had that same sex dream about bestselling author Dave Eggers. "I'm lying on the couch naked, and Dave is next to me, also naked, reading Salon on his laptop," said Dubar, a 34-year-old Iowa Writers' Workshop instructor. "Suddenly, he turns to me and says, 'Could you help me edit a collection of short fiction?' and I can't control myself any longer." Dubar said she always wakes up just as Sarah Vowell walks in wearing a kimono.
