At the time I felt like I became noticeably smarter. That may have been the arrogance of a 20-year-old, but the perspective shift was so vast that I was forced to think about things in completely new ways (for years after the trip was over). It definitely made my thinking much less rigid, regardless.

I also knew long beforehand that subjective experience is filtered by the brain, but having that fact forcibly shown to me was a whole other ballgame. I was also much calmer and more giving afterwards. I'm not sure why - maybe spending eight hours while super high and with a diminished ego makes you want to revisit that mindset.

Long after the trip and even occasionally today, I still see patterns in trees that are very reminiscent of how they looked while tripping. This may be a bit silly, but it's a nice cautionary reminder that my brain is capable of imposing order where there is none.

Superficially, I went from hating to loving electronic music, and felt euphoria for the first time.
