science of sleep

Miranda Kelly, a 14-year-old from Sykesville, Md., says she's been sleepwalking since she was 6 or 7. The first time, she says, "I woke up on the couch on a school day. And I'd gone to bed in my bed."

Since that first episode, Kelly now sleepwalks every couple of months. "I wake up in weird places, randomly. I have once woken up in the kitchen, and on the floor of the bathroom wrapped in my sheet," she says.
