It surely ain't just visual, you'll get a lot of mind-altering effects. Having said that, drugs have different effects on different people. To me, mushrooms are among the most visual psychedelics and still, the visuals are never as important in my trips as some other effects. I've just checked
erowid and I'll highlight the effects I feel the most, as I said, it may be different to you:
- mood lift, euphoria
- creative, philosophical or deep thinking : ideas flow more easily
- sensation of insight
- life-changing spiritual experience
Let me add one that's not on erowid:
- increased auditory perception (sometimes it means you listen with more attention, sometimes it means you feel music/sounds deeply, sometimes it means you are the music)
NEUTRAL
- feeling more emotionally sensitive
- time seems to pass more slowly (minutes seem to take hours)
- memories come to life
About that last one: I'm never sure if it's the drug itself or the fact that I know it's naturally available, but when I trip on mushrooms (or sometimes cannabis), as opposed to synthetic drugs like LSD or 2c-b, I get that feeling that it's being used by humans (and animals, why not?) for so many centuries that I feel I'm a link in a huge chain composed of ancient cultures, by-gone memories, old knowledge that we can try not to forget. All our thoughts, impressions, knowledge, fears, have been developing for millions of years. Yes, far out, I'm aware...
