Humans already live in a collective hallucination known as social reality. It’s a distinct overlay, distinct from our physical contextual realities and the phenomena we derive our physical laws from etc. overlay of what? Don’t ask. Variously explained as wiggles or turtles all the way down, or so I was told. I just wanted to point out that we flap our gums or thumbs a lot and ping concepts in each other’s minds via language, but speaking about stuff is not the same as the stuff itself.
