I wouldn't compare mushrooms and acid. Mushrooms feels very loopy to me. I lose my footing, start having verbal diarrhea and laugh hysterically and basically feel insane.

Acid was a more introspective, poetic feeling for me. Lots of patterns to enjoy, my speech was fluid and I could NOT for the life of me stop rhyming the things I was saying.

Everything felt artistic, everything. Lots of color and flow..... definitely a flow....the abyss. But I was much more able to process and use the information/feelings I was getting from the acid compared to any time I've used mushrooms.
