As of lately I noticed that there's always a visual component to my trip but most of the time I'm too happy to even notice them. From now on I'll try to look for hallucinations once in each trip. Like last time, I was pondering myself what could be in these pills we had, so I was "checking" my emotions and vision, and I managed to look at the same spot(footsteps in snow) for a few seconds. Things started morphing, circularly moving, extending, etc.
when the visuals get to a certain strength, I sometimes start noticing them suddenly when blinking, my closed eye visuals which linger, like after-images, cause some pretty dandy hallucinations. Like my field of vision is a cinema screen and my CEV-style hallucinations dance on the screen. This makes it look like my sight is 2D with an extra trippy dimension(depth)
offcourse in clubs with laserlights and dark spots visuals are easily triggered but still then I don't see them as hallucinations but it's just like the world is more beautifull which adds to my happiness. Mostly the visuals feel quite "natural"
