First off, do yourself a favor:
Forget 9gag. As far as I know it’s bad voodoo, I’ve only heard bad things about it pertaining to lucid dreaming, spreading all sorts of hysteria about certain topics of lucid dreaming, which is probably what your talking about with the “hallucinations” and “old hag”. Sure, some of these stories might be true, but come on. It’s even got “gag” in the name.
Now, as far as “theta waves” go, here’s the deal on them: Their a type of naturally occurring wavelength, and their any wave between 4-7Hz. Now, what does a wave have to do with dreaming? Well as it turns out, the brain’s wavelength patterns just so happen to measure anywhere from 4-7Hz when in the REM sleep cycle, AKA when you have dreams. We, being humans, cant perceive such a low frequency (so I believe), and so we try and perceive them through “bi-neural beats”, merely causing what’s called “destructive interference” between two waves. So say you’ve got a 10Hz wave and a 6Hz wave, slam 'em together, and whaddya got? 4Hz left.
Back on topic, by the brain perceiving these waves, it’s supposed to cause the brain to try and become “in-phase” by matching the wavelength, inducing some feelings you may not otherwise feel. Meditating while listening to theta waves can induce some interesting feelings, especially while trying to induce physical hypnagogic hallucinations or a split-mind effect. Note: Theta waves are only one type of wave the human mind can produce, each wavelength represents a different state of mind, each varying in speed and intensity. They go from highest to lowest in Gemma-Beta-Alpha-Theta-Delta, ranging from the highest state of physical consciousness to black-out sleep.
I’ll upload some pictures of some recent work I did into what they would look like compared to a natural frequency of 10Hz with a wavelength of 20m and an amplitude of 5, they should provide a bit of a better understanding of these “wavelengths”.
Now, as far as WILDS go, I wouldn’t obsess over them too much with so little experience. Sure, it would be great researching it, and meditating trying to induce SP or a split-mind effect, or HH, or even trying it as just practice, but trying it and expecting results without first having a few lucid dreams can make a person loose interest. Following a project with little to no results makes a person weary of the subject, and lucid dreaming isn’t something you want to lose interest in. I would say experiment in a few other areas, see what works best for you, and then coming back to WILD and really tackling it head on once you have the knowledge of what it is your facing.
Here are the pictures of the waves. Now, keep in mind, all the data besides the frequency(in Hz) is in relation the the harmonic-1, or the “fundamental”, meaning these are just what they should generally look like. I can’t really see what wave would have a wavelength of 20, dont ask me, I simply used it as an easy point of reference.
In order, thats:
T(cycle in seconds)=1/frequency
frequency(f) of a harmonic to the nth place=the place of the harmonic * the frequency of the fundamental, or harmonic1
wavelength=2L(length of an anti-node)
Rate® in comparison to the harmonic1=frequency/L
Explaining a bit of my madness, also that C, or 1C=one cycle.
L, or 1 antinode-10m, f-10Hz, A(amplitude)-5, wavelength-20m, v-200m/s, 1C-.1 second.
The harmonic-1, the fundamental, the keystone to all the research here. This natural frequency is nothing more than a vibrating string, but all the wavelengths being displayed here today are based off of this one little vibrating string. Funny how science works, eh?
Gamma waves in all their glory. The highest form of attention a person can give something, this is what your brain looks like when it’s bombing a calculus test.
Your usual state of consciousness, nothing special.
Note: The calculations for this wave is UNDER the “ALPHA” sign. This is both your brain on pot, and your brain while watching tv. Go figure.
These are what we’ve been looking for. These waves are what your brain goes through during REM sleep and while in dreams. This is the calming state of consciousness you’re looking for if you want either some serious meditation or a lucid dream/OBE/astral projection.
Delta waves. Not much to say here, if you’re going through this your either under some pretty heavy sleep, knocked out, or a zombie of some sort. Or maybe a vegetable. Either one, I guess.
At any rate, there are some gaps here, as you may have noticed. I had some issues calculating the wavelengths of the theta-delta waves, I decided not to write them seeing as they were just sort of…weird.
Hopefully these provide a better understanding of these waves in general. If not, and if your actually interested in them, read up on some more material covering the subject, they have plenty of material on the internet regarding all of this
