my friends and I got some VERY potent shrooms about 4 months ago, I took 2 grams and that was the most intense/longest shroom trip I ever had. It lasted us atleast a good 10 hrs and the peak was very intense, I could see outlines around people's bodys... like little lines outlining their whole body and everything I heard was echoing. I also had pretty intense visuals, everything I looked as was blending in together and morphing etc it was awesome
