I just did amanita, having only 3 doses of experience. The beginning felt like I was on a boat. Then my head was high above my body and I could no longer identify where my arms were. I had a short period of hallucinations followed by REM and the feeling of ants crawling over your body. There was a drop at 1 point which was a bit nauseating. I got very twitchy near the end. Btw, I used Condition before this. The after effect for me was the sound of random gusts of wind and disconnection from my torso.
