Luciding is now taking pre-orders for the LucidCatcher. (Lots more on this site about lucid dreaming). Like much of the tDCS research, studies report conflicting results using tACS to induce lucid dreaming. Note that Foc.us has had a 40 Hz tACS mode built into their V2 device and also has a lucid dreaming kit. It’s been out long enough now that I would think that widespread success with using it to induce lucid dreams would have been widely reported. The LucidCatcher does come in a form factor optimized for sleeping. I’m curious to know more about the unusual electrode setup.
How does it work?
We typically see the dreams during REM (Rapid Eye Movement) phase. The device detects your REM and pushes mild electric impulses to the prefrontal cortex at a frequency of 40 Hz. It brings the logical brain back into service and makes you realize that you must be in a dream.
You’ll recognize the dream by millions of different signs that contradicts the reality because your consciousness evokes.
Timing is everything.
Now if you update your foc.us v2 with the new 2.1 firmware you can set your stimulation to start in the future. Why? To sleep, per chance to dream.
It seems many of you are trying to recreate the Voss, Nitsche 2014 Lucid Dreaming paper published in Nature. So we have created a program with the settings and a timer for you to set based on your sleep pattern. You will still need to estimate when you will be in REM but the program has a 10 min window for you to aim at.
HatTip to Jay who is working on a tDCS/lucid dreaming project of his own.
tACS is transcranial alternating current, significantly more complex, from what I gather than tDCS. But perhaps a DIY tACS device set to 40 Hz specifically won’t be out of the question for DIYers. As someone who spent months (unsuccessfully) doing lucid dreaming exercises I certainly would welcome the opportunity to experience lucid dreaming.
The new dream study(paywall), which was published May 11 in Nature Neuroscience, used a far less invasive method: electrodes temporarily placed at strategic locations on the scalp. The research involved 24 volunteers with no history of lucid dreaming. The subjects went to sleep and eventually dreamed. Then, researchers turned on a 30-second-long electrical signal and then woke them up and asked them about their experiences. It turned out that a 40 Hz stimulation induced lucid dreams 77 percent of the time.
You can’t objectively measure a dream, though. So how did researchers know that the subjects weren’t just making it up? For one, the electrical stimulation was gentle enough that people couldn’t feel it, and some people were in a control group that had electrodes that never got turned on. Also, the study was double-blind: neither the volunteers nor the people who interviewed them were told who had what kind of stimulation. So it does seem that the effects were real.
