Maybe a tangent but in high school we procured some … not grocery store mushrooms, and whatever it did to my brain made me see the universe as a 3d hyperbolic honeycomb lattice. Though until today, I had no idea there was a name for that particular geometry. I wonder why these shapes show up so frequently in psychedelic art and experiences (anecdotally I’m not the only one who’s had a similar visual, by a long-shot).

Yeah there's this whole lecture about the hyperbolic geometry commonly seen on a DMT trip: https://youtu.be/loCBvaj4eSg?t=504 https://youtu.be/loCBvaj4eSg?t=504

  I've never seen hyperbolic geometry on not grocery store mushrooms... maybe I should try not grocery store DMT.

My guess is they are mid-layer activations in the brain that your consciousness (attention?) is connecting to, or which are being directed to the lower layers and interpreted as input.

  Are you saying that it’s the brain being conscious of the geometry of the light processing system? Kind of like the hidden layers of a neural network?

    Essentially, yes (we theorize). > It turns out that hallucinations comprising spirals, circles, and rays that emanate from the centre correspond to stripes of neural activity in V1 that are inclined at given angles. Lattices like honeycombs or chequer-boards correspond to hexagonal activity patterns in V1. https://plus.maths.org/content/uncoiling-spiral-maths-and-hallucinations https://plus.maths.org/content/uncoiling-spiral-maths-and-ha...

The shapes showing up during psychedelic experiences probably have to do with the geometry of our visual perception apparatus: Uncoiling the spiral: Maths and hallucinations https://plus.maths.org/content/uncoiling-spiral-maths-and-hallucinations https://plus.maths.org/content/uncoiling-spiral-maths-and-ha...
