Altered states of consciousness induced by breathwork accompanied by music

FWIW, I used to use a light and sound machine (Mindplace Procyon) and was able to induce these states with minimal effort. And I had a couple dozen experiences w/ psilocybin in my college years, so I'm well versed in what they should be like.

The goggles w/ binaural beats create some weird sort of state where I don't feel any connection to my environment. After only a couple minutes my body turns to total mush and my brain comes alive with phosphene visuals. By about 15 minutes in, my stomach usually gurgles a bit, not unlike the indigestion that often accompanies psychedelic trips.

Interestingly enough, these machines are marketed as brainwave entrainment, but the literature on that says the visual component doesn't really have much impact. Yet auditory entrainment on its own doesn't seem to do much for me either, or at least, not convincing enough beyond placebo.

There is an app for the iPhone called Lumenate that uses the LED flash and it seems to work, though it's not as strong for me as the multi-LED goggles I used to use. Still, it's a great gateway for those who are curious.

So you are saying this is more effective than foraged mushrooms in a dark dorm room - paired with a Winamp visualizer using real-time DirectX plugins and shader-based graphics? Forgive me for being a bit skeptical
