Gamma Wave Brain Zaps Induce Lucid Dreaming

Lucid dreaming is one of the coolest things we can do. People think that dreams aren&#x27;t real, but that&#x27;s far from the truth. They aren&#x27;t real in the sense that if I find a COOL WATCH or I win $2000 in a dream I can&#x27;t take it with me to &quot;real life,&quot; but when you think about what our life really is, it&#x27;s a collection of experiences...not accumulation of physical objects.<p>In dreams you can have the same <i>experiences</i> you have in waking life but even more so. You can take these experiences with you when you are done dreaming. Lucid dreaming takes this even further. You can imagine a problem you have is a tangible object (a bug or something) in your dream and squish it. Although this seems purely symbolic, you can take the feeling of having <i>dealt with a problem</i> into waking life, which will give you more energy to do the same in your interactions with waking life.<p>Not to mention in lucid dreams you can fly everywhere you want to go, you can have sex with whoever you want however you want, you can be a bear or a toad or a tree, you can be three of yourself at the same time, you can slow down time, you can travel to the bottom of the ocean and you can see distant planets or the inside of a star. Is it real? Yes, because you are actually having these experiences, even if you are the only one having them.

I first read about lucid dreaming 20 years ago when I was twelve. It was treated more as a new age fringe thing back then, but I had a blast experimenting with it. My favorite dreamscape involved a purely abstract state of mind where I could symbolically visualize components of algorithms -- nearly all of my work writing motion detection algorithms that worked in complex outdoor scenarios was refined in my sleep.<p>That being said, I eventually &quot;gave up&quot; lucid dreaming after 10 years or so. At a gut level it felt like sleep and dreams are best left to the subconscious -- a neural defrag, if you will. Personally I feel much more rested now that I make no effort to remember, much less control, my dreams.

Note: gamma wave, not gamma particles. Gamma wave refers to an aspect of brain activity. Maybe I&#x27;m the only one who was confused by the title but I feel better knowing people aren&#x27;t being irradiated for the experiment.

&gt;&gt; If I understand correctly, the participants rated their experience of these three factors on a scale of 0 (strongly disagree that I had such an experience) to 5 (strongly agree). Now if we look to see the scores they gave for how much dream insight, dissociation and control they had, we find that the averages for the gamma stimulation condition are around 0.6, 1.3, and 0.5 respectively. &gt; &gt; That’s a pretty low score, even if it’s higher than it would’ve been without the brain stimulation.<p>Maybe, maybe not. Averages work for some things, not so much for others. Suppose 4-5 are no-fooling-definitely-lucid dreams, and 1-3 are questionable. If the average is being driven by a few dreams falling into &#x27;5&#x27; and otherwise scores are unchanged, you&#x27;d get a worthwhile effect but only a small shift in average on your 1-5 scale. I&#x27;d want to read <a href="http://www.blogs.uni-mainz.de/fb05philosophie/files/2013/04/Voss-et-al-2013_Measuring-Consciousness-in-Dreams.pdf" rel="nofollow">http:&#x2F;&#x2F;www.blogs.uni-mainz.de&#x2F;fb05philosophie&#x2F;files&#x2F;2013&#x2F;04&#x2F;...</a> more carefully looking at how the overall rating distribution looks split by condition and whether the rating scale is masking a binary effect.

Since I was 10 I do lucid dreams. There are days that I struggle half a day to be 100% sure I&#x27;m awake and the other half to assimilate it.<p>For me this is really exhausting for three reasons:<p>1. the brain needs to properly sleep 2. they are so rich of details 3. they condense in 7&#x2F;8 hours maybe 5&#x2F;10 years of life<p>Basically they are what I think is a kind of parallel universe. I&#x27;m used to tell the entire &quot;dream&quot; to my GF. She always been astonished by them. They seems absolutely unrelated to anything I saw hear etc... during the day, they are in some case &quot;boring&quot; in the sense that I&#x27;m dreaming me in a totally different life, job etc... nothing &quot;exciting&quot; or &quot;strange&quot;.

Up till my early 20s, I used to lucid dream so much, I thought it was the normal state of dreaming (for everyone). Over the last few years the frequency has declined to maybe a couple times a month.<p>Of course, you never know how much you&#x27;d miss a thing until its gone. In this case, I didn&#x27;t even know <i>it was a thing</i> before it started fading away.<p>I&#x27;d certainly let my brain be zapped to get this <i>superpower</i> back.

I recently had a lucid dream for the first time. Really interesting experience. It was triggered by the fact that I plunged to a city at the bottom of the ocean and could still breath. I realized this was impossible and became lucid. I decided to try and have some fun with it so I &#x27;willed&#x27; myself to have a gun. It worked, kind of. I had something in my hand that i could shoot with but it was sort of undefined. Kind of like if you are playing a 3d fps and the texture for your gun doesn&#x27;t load properly. It was kind of amorphous and brown and glitchy. I suspect because I don&#x27;t know a ton about guns and i didn&#x27;t really specify what kind of gun or anything. Perhaps next time ill imagine an ak47 and see if I get more definition.<p>I played around shooting things for awhile but it was draining to keep control so I gave up and became batman, was knocked off a bridge, and broke my back on a cement pillar. I woke up screaming &quot;You just killed Batman!&quot;.

As a graphics nerd, the handful of times I&#x27;ve had genuine lucid dreaming (when experimenting with it in college) was incredible. In the dream I would would focus on taking in the behavior of light and texture on surfaces and trying to gauge its quality from a computer graphics perspective, and always found the &#x27;simulation&#x27; absolutely stunning. I remember encountering a large rabbit once and ran my fingers through it&#x27;s fur and it felt and looked real. It&#x27;s mindboggling how well the brain can simulate a fake environment when you go lucid, it&#x27;s really beyond comprehension to me how it&#x27;s able to do so. The brain can basically simulate the rendering equation in real time (or trick yourself into thinking it is, which is the same thing really.)

If you want lucid dreaming without having to wait for a Gamma Wave Zapper, there is one alternative. Sertraline (Zoloft). I&#x27;ve been on and off of it a few times in the past 10 years for anxiety. After a few weeks of being on it, the lucid dreaming kicks in. Sometimes I wish I could record these dreams and make them into movies. It&#x27;s quite the experience.

&gt;The sweet spot was 40 Hertz. Zapping sleeping volunteers at this frequency, part of the so-called gamma wave band, led their brains to produce brain waves of the same frequency, the researchers found, which triggered lucidity 77 percent of the time, as determined by self-reports from the dreamers after they were awoken.<p>&gt;Now if we look to see the scores they gave for how much dream insight, dissociation and control they had, we find that the averages for the gamma stimulation condition are around 0.6, 1.3, and 0.5 respectively.<p>I don&#x27;t understand. A score of 0.6 for insight means, at best, 40% strongly disagreed that they knew they were dreaming and 60% perhaps <i>moderately disagreed</i> (score=1). Some higher scores for the successes would result in even more than 40% <i>strongly disagreeing</i> that they knew they were awake. I could see it having an effect for a small number of people, but how does that translate into &quot;triggered lucidity 77 percent of the time.&quot;

Highly interesting effect, but note that the extent of lucid dreaming here is (self-) reported to be rather low:<p>&quot;<i>Despite the robust methodology, I think these headlines are getting carried away. Here’s why. Lucid dreaming was defined by higher scores in participants’ feelings of insight (knowing that they were dreaming); dissociation (taking a third person perspective); and control (being able to shape events). I looked up the paper where the researchers first described their scale for measuring these factors. If I understand correctly, the participants rated their experience of these three factors on a scale of 0 (strongly disagree that I had such an experience) to 5 (strongly agree). Now if we look to see the scores they gave for how much dream insight, dissociation and control they had, we find that the averages for the gamma stimulation condition are around 0.6, 1.3, and 0.5 respectively.</i>&quot;

I had my first lucid dream when I was 16 years old. About 10 years ago I had a dream that I can only express as a self induced DMT experience. It happened during a time where I was in an extreme amount of &quot;outside of myself&quot; anxiety. I didn&#x27;t know what DMT was at the time and only drew parallels after the fact from listening to interviews and reading a book on the subject. Since then I&#x27;ve had a few lucid dreams where I&#x27;m right on the verge of &#x27;ripping open the universe&#x27; in DMT-speak. Anyway, it was life changing to say the least so I enjoy articles like these.

People are already making DIY transcranial direct current stimulation gadgets for themselves. The setup apparently isn&#x27;t much more complicated than a regular battery and two electrodes taped to your scalp. Someone at Reddit also seems to be working on making a consumer device for the lucid dreaming thing: <a href="http://www.reddit.com/r/LucidDreaming/comments/25aos9/published_in_nature_neuroscience_today_lucid/" rel="nofollow">http:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;LucidDreaming&#x2F;comments&#x2F;25aos9&#x2F;publis...</a>

I wonder if staring at 40Hz refresh rate screens could produce a similar effect? I have a screen with a flickering backlight at a frequency just outside perception. If I use it for prolonged periods before bed, I can perceive a &#x27;flickering afterglow&#x27; for minutes while trying to sleep.

The half a dozen or so times I can remember lucid dreaming I always try to fly. The only problem is that I start floating and can&#x27;t control it and I start tumbling--it feels exactly like the point when you&#x27;re tipping back in your chair and you realize you&#x27;re going to fall.

I find normal dreaming much more fun. It&#x27;s like playing Stanley Parable for the first time, instead of of opening Garry&#x27;s Mod...alone.<p>I&#x27;ll pick a Stanley Parable any day over Garry&#x27;s Mod.
