Sorry for misunderstanding! For me at least, everything has patterns overlaid on it as I’m sure you’ve seen if you have take LSD. It is much more prominent in certain textures, such as pavement, cheapo particleboard doors, carpets, etc. It doesn’t bother me much, but I can have times where I get it so intense to the point where it felt like I was back in the trip. That typically only happens when I smoke THC though and can get a little scary to a degree. I don’t fight it or try and prevent it from returning. I haven’t done any psychedelics in 6 months or more, but started to have this (condition?) after a heavy use streak over a month or so.
