Scientists zap the brain for lucid dreaming:
"I never thought this would work," said study researcher Dr. John Allan Hobson, a psychiatrist and longtime sleep researcher at Harvard University. "But it looks like it does."Of course, that's not always a pleasant experience...
The results showed that when the inexperienced dreamers were zapped with a current of 40 Hertz, 77 percent of the time these participants reported having what were described as lucid dreams.
"They were really excited," said study researcher Ursula Voss, of J.W. Goethe-University Frankfurt, who designed the experiments. "The dream reports were short, but long enough for them to report, 'Wow, all of the sudden I knew this was a dream, while I was dreaming.'"
