There is definitely something to this stuff.

Shortly after typing my last rambling, I switched it to a standard theta wave with some pink noise, and laid back on the couch with my headphones on. Gradually, I started sinking off into something that almost resembled a light sleep, but it wasn't sleep, because for the longest time, just as thought started to leave my mind, I would wake back up. Many times, when I would start drifting off, it sounded like I could pick up all sorts of little sounds in the noise, like rhythms, beats, clicks, and melodies, but whenever I forced myself to focus on it, I would only hear the noise again. Then I would go back to imagining other things, like in a half dream.

After a while (I didn't actually time it), I guess I sort of did go to sleep. I was startled when my phone started vibrating in my pocket. Somebody was trying to call me. But my head was so deep in it that I didn't answer the phone at first, and called back a few minutes later. It wasn't that I was really sleeping that heavily, but my mind was in another world. I took the headphones off, and it took several minutes before my head came out of the daze.

I guess it wasn't that long, because looking at the clock now, I know I couldn't have been under for any longer than an hour at most.

Wow, that was trippy. Right now, I've got the beta waves running (but not long enough to have any effect just yet). Cool stuff.
