In lucid dreams, people are aware of the fact that they are dreaming, and can control their dream plot.
Lucid dreams, in which people are aware of and can control their dreams, are rare. But now scientists have found they can induce this weird state of mind in people by zapping their brains with a specific frequency of electricity.
"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."
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.'"
