i did shrooms twice. the first time i didnt take enough and just felt really high (no visuals).
However, the second time (last summer) i did them i took 2.5 grams of some pretty good shrooms and had a great time. It was just my older brother and myself. My brother did not take any because we didnt have enough for both of us. So, he just smoked some weed.
After I took the boomers, I felt really high and really happy. I would have random outbursts of uncontrollable laughter. I jumped on my trampoline for a little bit, but it seemed really intense on shrooms (i dont know why, haha) so I got off the trampoline to experience some other stuff. As I was walking around in my back yard, the visuals started kicking in. I looked up at the clouds and was mezmerized. The clouds were "breathing" (a common wavy visual effect of shrooms). Also, I saw the clouds turn into very distinct shapes, but only for a couple of seconds. One cloud looked as if it turned into a huge eagle - by far the best visual i got. it was amazing. I also saw skulls on many different things (clouds, trees, rocks). These skulls were not frightening as you may think. But instead, I was very interested in them, and they did not scare me at all. I would stare at them and they stared back. When I went to touch them, they vanished, and would return when I had more distance.
My mom was out of town, and left her BMW at home. So, my brother drove around in the Beamer as I rode shotgun and watched the environment zoom by. I could not stop laughing the whole time we were driving around. We eventually went home and smoked another bowl. My trip lasted about 5 hours and then the visuals started to fade away.
I am excited to do shrooms again since I havent done them since then.
Do not do them very often at all though, it will fuck you up in the long run. Be responsible, and have fun!
Note: If you do shrooms while you are feeling bad or uncomfortable, you will have a bad trip. It's all in your mind. Just think "this is going to be a great time!", and you will have a great trip. If you see something that is frightening while tripping - just tell yourself it is not real, and you'll be fine.
