Completely unlike anything else. Can't accurately explain it better than that. You teleport to another dimension is the best way to describe it. One inhabited by friendly thingamabobs that bounce and speak and sing and romp and play and build. Thingamaboibs that sparkle and change shape. Happy thingamabobs, but they are quite serious at the same time. All of them flooding your head with words somehow...but not really words at the same time. And you only remember your impression of it when it's over. Not the details. Like a dream.
Most folks I know who have tried DMT experienced the same thing . Kinda sorta. Can't explain. It's deeper than that. The thingamabobs seem very important somehow. Obviously an hallucination, but apparently most folks have a similar hallucination. Heck, I can't even really remember what the thingamabobs looked like, or the surroundings, or much else - just that they were there, moved around a lot, seemed very very happy to see me, and urgently had to tell me SOMETHING, and they did, but I can't recall what. What I did recall I recalled because my friend had me IMMEDIATELY start talking about what I had seen as I was coming out of it.
Only did it once. Got it from a deadhead friend back in the 90's. Lasted about 5 minutes. You still have your sense of time, you still feel like your same old self, just transported away to this weird and wonderful place. Orangy crystals. It burns like hell when you smoke it. Needed to do about 3-4 good hits. Felt like I smoked razor blades.
I asked him to get me more, but he informed me it was "sacred" and not ordinarily for "folks like you" -- whatever the fuck that meant. Elitist hippy asshole. Never saw any of it again.
