Seriously, though... Is there some fractal geometry to the way our neurons are interconnected/communicating that's responsible for producing the kinds of visuals we see under the influence of certain substances? Or do we still have way too much to learn about the brain before we answer questions like that?
It's more that many fundamental laws of our reality are fractal-like and as we impair our critical thinking functions and neural circuits with psychedelic drugs, these underlying layers are revealed.
That's my theory, anyway. Based on nothing but vibes.
I mean, yeah. I don't think there's anything supernatural going on, like making contact with other life forms in some alternate plane of reality or whatever. But it is curious that lots of people report seeing the same sorts of things under the influence of various psychedelics. All I'm saying is that there is an explanation to be found, even if it ultimately ends up being disappointing. At least until then, I feel like it's going to remain interesting to me.
