Awful Experience

Ok i got home from school and my freind called me and told me that he had just bought 1/2. We each did about 2/8 and after about an hour i knew that something wasnt right. I had done shrooms 10 or more times and it was nothing like this. I suddenly felt like i was inside my freind and that my soul was trying to break through him. He was talking to me but i couldnt respond. HE kept saying stuff like how he feels weird and about how this isnt normal. And hour or two later i had completly lost it from reality. I could only see colors and waves, no objects. I kept hearing voices telling me how i feel. I was trying to figure out what my thoguhts LOOKED like. At this time everything went black and i passed out. (aside from my knowledge my friend had been passed out for over an hour. When my parents got home really late that night they thought we were sleeping and did not try to wake us up. Around 12 the next day we woke up. This has never happened to eather of us and we think there might have been something wrong with the shrroms, (i.e. laced or sprayed with something) Does anyone know if it could have been laced? Thanks
