Your Dreams Can be Controlled by Electrically Stimulating Your Brain
It appears that applying an electrical current to your brain not only boosts your cognitive powers, but it can also help you obtain the mystical ability of lucid dreaming, where you can control the plot and outcome of your dreams. These findings come from a new study that found that lucid dreaming could be induced in a full 70% of participants, with a simple (external) electrical current passed across the frontal lobe. This has obvious applications for body hackers — but perhaps more importantly it may have a medical use, too, in helping people who suffer from chronic nightmares.
A lucid dream, if you haven’t heard of the phrase before, is a dream where you know that you’re dreaming. So the theory goes, if you’re aware that you’re dreaming, you can then exert some kind of control over your brain’s imagination, resulting in some very fun, wild, and vivid dreams. Some people report being naturally lucid dreamers, while body hackers try to artificially induce a lucid dream state with various different techniques (mostly involving meditation or setting an alarm for a few hours after you fall asleep). Scientifically, some studies have shown that during lucid dreaming there’s increased activity in your brain’s frontal and parietal (top/side) lobes — regions of the brain that are involved with higher-level conscious thought. Skeptics think that lucid dreaming is more like small snippets of wakefulness interspersed with normal REM dreaming, rather than a bona fide dream state.
In this study, the researchers — mostly from a bunch of universities in Germany — asked 27 men and women to spend a few nights sleeping in a special sleep lab in Germany. After the participants entered REM sleep, where most dreaming occurs, an electric current was passed across their skull, stimulating the front and temporal lobes. The researchers found that when the electrical current was a very specific frequency — between 25 and 40Hz — a full 70% of participants experienced lucid dreams. When no current was present, or the wrong frequency, not a single participant had a lucid dream.
