Pink Floyd gone wrong!

To start off my first trip off of hydroponic mushrooms wasn't what i expected at all. Im used to doing the little brown guys from off of cow paddies. Well I had about 5-7 grams at 9:00pm and we smoked 2 bowls. Then we all got the giggles. Some time passed and all of a sudden nausia came over me and i puked then time started going really slow. I completely lost my mind. I didn't know what to do. I was feeling like if i was going to die, asking my friend to check my pulse and my temperature. The nausia never passed. I saw some slight visuals but nothing vivid. I was in a bad mood. I couldn't talk to people, couldn't stand people talking to me and i didn't want to be touched. I kept having to calm myself down and reassure myself i wasn't going to die. It also was very hard to swallow. About 2:30 a.m i snapped out of it and ate a ham sandwich. I went to bed but ended up going to sleep 2 hours later at 4:30. When i got up the whole day i felt as if i was floating. That was a pretty bad experience . Does anybody have any trips similar or know of anyway i can avoid this kind? Thanks
