very bad trip

me and 5 of my friends all ate an 1/8th.. i'm not sure what kind.. but we all ate very large caps and not many stems... all of us had a bad trip.. 3 of my friends had seizures and 2 of my sober friends almost called 911 because we thought they were going to die.. i threw up... and my one friend had a horrible trip.. he thought he died.. everyone sobered up and they worth off except for him.. he sat in a chair and like he was asleep but with his eyes open for 3 hours.. and all of a sudden he woke up and didn't believe what was going on.. his trip was so real he thought he was in heaven and we had to explain what was going on.. he was lost
