too many for my friend to handle

Well this was the 2nd time i had ever tried shrooms and the night before me and my friend Casey decided to buy 3 1/8s of mushrooms because we wanted to invite sombody else and each take 1/8. The next day we went to the bowling ally wihout anybody else and each split up that whole bag and took them. about 10-15 min later we felt a little different and decided to take the bus to a movie. I was seeing things and noticing things were different but surprisingly nothing was TOO different. By the time we got to the mall my friend was tripping out. he could barly talk and was forgetting where he was. about half an hour later he was in another world. He would walk right into things or see like doors and like they were not there. By this time i could feel the fungi taking effect but i knew what i was doing and followed him up a staircase in which he threw himself down not even knowing what he was doing. He was fine and it just kind of stunned him. He continued walking aimlessly around for another hour or so and threw up on and off. We walked back to the end of the mall where the exit to a movie theature was and his pants were falling down and he just whipped out his manhood and started masturbating not knowing what the fuck he was doing and he fell to the ground and started twitching but soon stopped and continued doing this kind of weird shit. I decided to call my mom (as i'm 15 and she knew what we were doing) and have us get picked up and chill at my place so i left him on the ground and ran to a payphone as fast as i could. By the time i got back there was a large amount of people laughing and asking if me if this kid was just playing around or if he was really masturbating i ignored them and continued walking until i saw three cop cars pull up. They asked me what happened and i said he took to many mushrooms and that it would be a better idea to take him to the hospital instead of the police station so they did and he got in big trouble but snapped out of it about 6 hours after he ingested the shrooms... I'm curious to know what happened to him because nothing like tha thas ever happened to me.
