Thread: Naturally increase Acetylcholin level makes you lucid?

So if I take supplements to higher my acetylcholin level in brain, there is much higher possibility that i will go lucid.

My question is does other techniques without supplements like mild or wild meditation higher your acetylcholin level naturally or is it non acetylcholin mechanism at all.

I mean everything in brain has to be physical right? The awareness, reality and everything is just a cause of processes in the brain.
