Very fun thing that can happen on heavy doses of hallucinogens: seeing your thoughts visually. His experience of seeings geometric patterns that shift depending on what/how you're thinking is what I've seen too. It's like putting every thought in a multidimensional space that includes color, and going around it while thinking. Similar thoughts or thought threads look similar in color, shape and texture, while jumping from one thought to another can be almost strobe-like. Going deep into a thought can make it materialize from the weird neon geometry mash to something resembling hyperrealism. I didn't find it a very spiritual experience actually. It was like playing with the visual part of the brain and seeing what the hardwired stuff is, felt very physical. The Dreamachine seems similar in that regard. Another weird parallel: when AIs create those pictures of stuff that looks like something but under further analysis is just random parts of different things it's similar to the hyperrealistic bits' texture.
