I had ket a number of times, in various forms, usually in the after hours of MDMA nights. I never really felt like I 'got it'.
First time I had MXE, I became heavily intoxicated very quickly and felt charged up with nervous energy. I had difficulty stopping at the crossing of a highway. Birds flew past in glitchy slow motion and I couldn't understand why some guy on the street was asking me if he could 'have a cigarette'. Of course he could - he can probably do anything if he really sets his mind to it. Just has to have a can-do attitude. I tried telling him this but he became quite hostile. The whole day, it wasn't a good experience.
The last time I did MXE I laughed for like 48 hours straight about this time, maybe 15 years earlier, when I saw a guy fall down some steps and break the photocopy machine he was carrying. It was like a live comedy sketch. I literally felt like I was drifting down a stream of pleasant memories, reliving them inside my head. That was a great experience.
Since then, I've just had MXM, which I found generic. Kind of black and white.
I don't think I will ever have dissociatives again. I fell out with a friend because I couldn't handle the way dissociative use was affecting her, but I couldn't say anything because I'd sound like a total hypocrite.
Not sure why I typed all this out tbh, but that's basically my history with dissociative drugs. Glad they don't really appeal to me as it would just be one more thing to deal with..
