What's up nexians I'm curious if anyone has ever tried or thought of trying audio/visual brainwave entrainment and psychedelics such as lsd,dmt, or salvia? I've read a lot of crazy stuff on mk ultra experiments , the Philly experiments and the camp hero experiments as well as reading tons of physics articles on dimensions and how vibrational frequencies like theta waves cause your brain or consciousness to retune itself like a radio to perceive different realities. I'm not saying any of this is or isn't true but it seems like you hear reoccurring things in these theories(vibrational frequency, altered conscious and other dimensions).. Any thoughts?

Neural oscillations are important to states of consciousness. There was an experiment where entraining high frequencies via electrical stimulation during REM sleep resulted in lucid dreams. Also, many anecdotal stories about entraining high frequencies resulting in a more awake, refreshed mindset. So yes, it's definitely a thing, and would be pretty interesting to experiment with during psychedelic trips...

That said, I'd rather not confuse neural oscillations with the whole quantum-hoodoo parallel universes stuff.

I've used brainwave generator lots of times over the years, it has plenty of uses but the effects are a bit more subtle than "different realities".
check out this album with a light dose of your psychedelic of choice for an interesting experience:

Will do ...

The book "Into the Void" by 'Zoe7' covers this very topic. Seek it out.

I’ll check it out on google... I plan on getting a brain entrainment head set putting a vr headset on with the Mandelbrot set zoom and visiting the sage diviner and see how it goes. Wish me luck peeps
