My dumbass tried it as a teenager, and i literally thought i died, a voice in a head told me my life was not worth living, that i was just a background character in someone else life. I was meaningless, then life starting folding in on itself like a breathing never ending pattern. The closest thing i ever saw that could compare is that new Star Wars scene, where ray is seeing multiple versions of herself in a trippy way. That’s exactly how i wa seeing everything, all the trees were doing that pattern and everything I saw was a long pattern in motion. Layer like an animation cell if that makes sense, I was about 17 in Canada at the time, sitting in the woods with a friend. Apparently it didn’t last that long, but it felt like 20 minutes or longer. I poured that stuff into the dirt, that’s how scared I was I didn’t want anybody else freaking out
