This was from yesterday's New York Times - an article called 'Living Your Dreams, in a Manner of Speaking'. It talks a little about the concept of lucid dreaming, but also focuses on a new movie being written and directed by Jake Paltrow called "The Good Night".
Living Your Dreams, in a Manner of Speaking
Established sleep researchers say lucid dreaming is occasionally reported by subjects, though it is difficult to validate scientifically. “Yes, lucid dreaming exists,” said Dr. Rodney Radtke, the medical director of the Sleep Disorders Center at Duke University. “Yes, people certainly can, within their dream, realize ‘this is just a dream’ and continue to participate.”
“Do I believe that someone could potentially alter or interact with their dreams in such a way that they could change the dream? Yes,” he said. “Do I think that you could essentially design a dream — ‘Oh, I want to go to Honolulu and have this big hunk hit on me’? It’s a bit of a stretch. But I can’t say it can’t happen.”
He added: “Only in New York or California do they worry about this stuff.”
Stephen LaBerge, a psychophysiologist and the founder of the Lucidity Institute (lucidity.com), conducts lucid dream research and
teaches people to do it.
“It’s kind of fun to do the impossible,” Dr. LaBerge said. “Fly. Dream sex. That’s what everybody likes to do. There’s also the possibility of creative problem-solving, overcoming nightmares and anxieties, learning more about yourself.”
A student at Stanford University, where Dr. LaBerge conducted much of his research, wrote in The Stanford Daily: “In one of my earliest experiences with lucidity, I announced to an auditorium full of people that I was their god (wasn’t I?). When they did not respond deferentially, I used telekinesis to send one of them flying across the room.”
It can be particularly appealing to those who have nightmares, as it allows them to realize while still asleep that they are just dreaming.
Interest in these potential real-world benefits and the otherworldly freedoms of lucid dreaming — as well as the questions it provokes about the precarious nature of reality — has spurred the invention and evolution of seemingly wacky dream aids. There are masks with lights and sounds; Orwellian devices that announce THIS IS A DREAM! in the middle of the night; and pills.
At the Hawaii gathering next month, attendees will be able to check out Dr. LaBerge’s NovaDreamer, a mask meant to light up during REM sleep and cue the person entangled in the sheets that he or she is dreaming. It is based on the notion that people can make a plan while awake and then execute it in their dreams. A light or sound is meant to remind them of their goal of lucid dreaming without actually waking them up. Participants may also take part in experiments with an herbal version of a drug that impacts acetylcholine, a neurotransmitting compound that affects memory.
As bizarre as these things may sound, there is a scientific rationale for cueing users during REM sleep. “REM-sleep dreams are much more visual,” said Matthew P. Walker, the director of the Sleep and Neuroimaging Laboratory at the University of California, Berkeley, and a former assistant professor of psychology at the Harvard Medical School. “They have a strong narrative that runs through them. They’re hallucinogenic.”
There are several reasons for this, including that the lateral prefrontal cortex, the part of the brain involved in logical reasoning and working memory, becomes more inactive during REM sleep, while other areas of the brain, like the visual and emotional centers, rev up.
Scientists, however, are still trying to discover the difference between the dreaming brain and the lucid-dreaming brain. The leading candidate, Dr. Walker said, is the lateral prefrontal cortex. He thinks that during REM sleep, the activity level of this logic-oriented part of the brain begins to rise back to waking levels, and when it does, an invisible switch is flipped and the sleeper gains lucidity. “In the next five years, I think somebody will demonstrate that,” he said.
Lucid-dream researchers say there are myriad mental exercises a person can do during waking hours to try to become cognizant while dreaming. One technique involves performing various reality checks many times a day — such as looking at the numbers on a watch, looking away, and then looking at them again to make sure that night has not suddenly become day. The theory is that if a person does this regularly while awake, he or she will likely repeat it while dreaming and will recognize inconsistencies — if, say, the watch is melting in a Dali-esque way. Then the sleeper will think: “This looks surreal. I must be dreaming.”
