Just so you know, lucid dreaming is a proven scientific FACT. It's not some new-age spiritual thing, it's simply a scientifically accepted fact that if you know you're dreaming, while you're dreaming, you have complete control over what you dream about. And telling adolescents that they'd be really interested in a psychology class focusing on the stages of sleep isn't a very wise thing to do; when I meet a 15-year-old who's obsessed with theta- and delta-brainwaves, I'll change my mind.
