That sounds like an interesting experience. Nice track btw.
When I'm in the process of making music I usually lay down the basic structure of the track and have it loop while I imagine other sounds. I agree it's sort of like meditating, sound is a wonderful tool.
I'll tell you what though- I was messing with my synthesizer a couple months ago, and getting some weird sounds out of her, I had headphones on at a low volume, they're AKG 240s. The sounds were so lush and euphoric, I started to increase the volume slightly. I took the headphones off after a while to avoid ear fatigue, went to lay down, and it felt as though I smoked some cannabis. It was a smooth relaxed high, and I was able to think deeply, exactly the effects I get when I smoke cannabis.
I ended up falling asleep and having a weird dream. I was laying down and there was flat-screen monitors everywhere with random images or videos. I can't remember what I saw too well, I'm slowly forgetting the dream, it looked like the future, or at least it seemed so. There was a female voice talking to me, then all of a sudden I woke up and wrote this down on my iphone-
"The universe, and all that we do is controlled by uncontrolled energy. Energy is controlled, measured, and defined by sound-waves and frequencies." 5:55am 3/18/2011
I don't completely get it yet. Well I do, but I can't explain it thoroughly enough without getting ridiculed. This is what leads me to study mathematics and physics. Sound is an energy, an underestimated one.
