I went to a college party last Thursday. I took a big hit from a grav bong. The high started to settle in, but then it got more intense, my brain felt like it had 100s of super balls bouncing around. I fell in an out of consciousness, I couldn't talk or read, I kept hallucinating these strange patterns. I tried to drink and vomitted everywhere. I can only explain the experience in one way, it felt like death, the whole time I felt like I was keeping myself from dying. My breathing was odd, and when I felt like my life was slipping, I would force myself to breathe deeply. What happened to me? Everyone at the party claimed they never saw something like that.
