It's almost impossible to describe to anyone who hasn't experienced it. Even then, everyone has a different experience. The strongest/longest visuals I've ever experienced were from four doses worth of mescaline. Took it at 8:45 in the morning, visuals didn't subside to an afterglow for almost twenty four hours.

Once I was invited to eat some shrooms with these two girls I knew, got to her place and she tossed me a chocolate star about the same diameter as a Reese's cup but twice as thick. It had five points and a dime sized center. I ate the whole thing. She sees me chewing and asks how much of it I ate really concerned like.. Turns out it was equivalent to a half ounce of shrooms. Her walls were solid color and warping within the hour. Her cats fur was moving so strangely when it was breathing and staring at me so intently. I was fucked. It was brighter with my eyes closed then when they were open. I drove home around five hours later, still tripping my balls off but I just had to get out of there. Went back to my apartment and my roommate said I was asking ridiculous questions, 'why is Pamela Anderson even considered hot?' But really intently, like demanding answers. Anyway. Make sure you know how much drugs you're taking, and never underestimate shrooms.
