Interesting. It could suggest that you formed some permanent new connections between some unusual parts of the brain. My own experience was kind of opposite so far. In the beginning I had pretty apparent visual illusions, like wall corners, patterns breathing, or actually seeings beams of light shaped by different music, even on 100ug. But over time it seems my brain was somehow adapting to it. On many following trips, the visual illusions become more like 'shaking' a little bit, just some noise. I started to think that either the acid's gone bad or I had a different kind of sorts. Some time ago, even on 300ug, i had almost no visual illusions (which was quite disappointing, as I expected the music to still bring it). Instead, I have a more vivid imagination.. But it's not visual, just more like if you think of some scene from memory.
