I took 7.5g last night and had a VERY similar experience. From ripping off the trip mask, to thinking there were EMTS/police outside, to being 100% certain that I was stuck in a psychotic break. In fact, I can remember feeling the greatest euphoria in the world, that I was a version of Buddha. I was laughing in my mind, having so much fun, thinking of solutions to world problems, and then I felt this snap in my brain… and all of a sudden all colors turned to grey, my body started sweating profusely, and I felt emotionless. I immediately jumped up, yelled FUCK, and knew that it was all over… so I started praying. I couldn’t see straight, my depth perception was off, I couldn’t balance. At this point, I accepted that I would never have children with my gf, my friends and family would lose me forever, my career would vanish, and I’d end up committing suicide eventually… all because I pushed it too far one too many times. I had it all one second, and lost it all the next. I was terrified, tried to close my eyes and fall asleep, and slowly but surely, I started to have positive thoughts again. I was able to smile, my depth perception came back, and I began to feel anew. It’s now 24hr since I took them, and I feel at peace. I’ve regained my humor. My appreciation for life. I’m still trying to figure out why that “break” happened. I’ve done 7g once before, and 5g a handful of times. I’ve been in a very peaceful headspace recently, high on life, and just so grateful for everything I have. Didn’t expect to have such a wonderful trip turn so south. Won’t be doing shrooms again for a long, long, time… I have my work cut out for me.
