I was in my friends backyard with a big group of friends and we were taking turns passing around the bong with Sally-D 20x in it. We each took a full bowl of the water bong and held it in for 30 seconds. When I took the bong i got a bit nervous but took my hit and held it in. 30 seconds later i blew out my hit and the world started to swirl inwards and i thought this was funny so i laughed. Then i got up and thats when things got weird...
I couldnt see what was in front of me and i forgot where i was, who i was with, who i was, and i forgot i was a person. All i could see where this triangular shapes spinning at me and i thought i was one of those shapes, and its been like that forever. I remember saying in my head "being a shape sucks."
Those visions continued for a while and i thought there were different classes of traingles and a soceity of traingles and its been like that always and i forgot what being human felt like as all these shapes flew by me. When i started coming back from it the world spun back into normal shape i was on a step sitting down looking at the ground and my friends were either taking a hit for the first time, tripping balls, or just sitting thinking what just happened. It was the single most trippy experience ive had in my life.
