everything vibrates. for example, i am a high frequency vibrator ;-)
btw, the predom color experienced with DMT is a spot-on indicator around which chakra the individual construes his 'reality' aka where he be thinkin outa...
Very interested to know this. I have done some chakra meditation, but I am not very well versed with it. I have experienced a conscious opening of the third eye chakra, which was very strange. It was like a second field of view appeared in the middle of my forehead, as though there was a window I was looking through. Freaky.
ETA: Do your experiences with binaural beats match the descriptions on the wiki page, i.e. for each of the frequency bands (alpha. beta, gamma, etc), do you get the described effects? Have you tried it at high-gamma frequencies (between 80 and 320 Hz)?
I cannot answer this definatively. I used the Monroe approach to the binaural beats and he did not define it this way. He called the various states "focus states." Focus 10, for example, was the state of your body being deeply relaxed and almost asleep but your mind being awake and conscious. In my experiments with the binaural beats, the recording that was meant to take me to "focus 10" did, in fact, produce a mind awake body asleep state.
I am moderately ashamed to admit that I downloaded all of this and did not purchase it. As a result, I was missing certain recordings. I did not want to advance in the wrong order because it was a learned meditation process. So, because I was missing the tape that followed focus 10, I never really advanced.
However, a friend had some additional recordings, and she had one that was meant to be a deeper focus state, and when I listened to it I almost immediately snapped into a very deep meditation state that was different than focus 10.
So, in my experience, they worked and they did produce different results based on the recording you were listening to.
Another aspect was that at this time in my life I was having some emotional struggles. The recordings were producing changes in the way I fell asleep and woke up. I was experiencing a lot of sleep paralysis and hallucination and although it was often directable into an out of body state, it was also somewhat disconcerting because I was living alone. I would wake up in the middle of the night and see people in my bedroom talking, or hear conversations in my closet and be paralyzed. Some nights that was fine, but some nights I just wanted to sleep and it was freaky. So I stopped using the recordings.
I agree with you that DMT takes you within your own soul... to that place that is completely innocent and egoless... the place that we can attain without the aid of drugs if we devote our lives to it
