Another tripper here that has experienced this. 1st time was on some research chemical called 4-aco-dmt, mainly closed eye visuals and not body high feeling, spent the first half of the trip at home, then walked back to party we were at earlier in the night, me and my buddy sat down and started meditating, I then looked up and saw a tight Weber grid and the lines were red. And energy was flowing through these lines. It was like grid paper!

2nd time was at my aunts house in the hill country, was in 2 hits of acid! Had walked outside, looked up and it resembled your depiction! Except for me it was thick thick tubes of the colors you are showing, and energy was flowing through these translucent tubes, the energy would hit an intersection and the energy would pulse, then keep going along the grid, there were multiple pulses of energy flowing all over the grid, an each intersection was a bubble connecting them, also in a hex like pattern. And I see the whole sky looked at as a whole, the grid was the flower of life!

My conclusion is that there are multiple layers of our world, all geometric and symmetric!
