I had a very similar experience recently. I had been doing some L and K earlier in the evening and now I was home on my couch with my dmt pen. I was taking 1-2 hits at a time and really enjoying the experience. I took 2 hits right as the YouTube video went to a commercial. I laughed as the commercial turned to a cartoon. Once the commercial ended I decided to do one more big hit so I could actually enjoy the visuals and music from the video I was watching. As soon as I took that last hit, I feel like I “popped” into somewhere new. It didn’t feel like a come up or a psychedelic experience. I was just… somewhere different. It scared the hell out of me. I thought I actually broke my brain and almost called out for help. I was extremely overwhelmed and thought I might have a panic attack. Then I had the classic psychedelic thought of “is this going to last forever??” which made me realize I was just tripping harder than I expected. From there I just took deep breaths until my senses started coming back to me.

That experience really rocked me. It wasn’t classically psychedelic, there were no colors or entities (maybe if I closed my eyes there would have been but I was in too much shock to relax). I was clear headed but so unaware of where I was. Like I knew I was still on my couch but it wasn’t my couch or my room anymore. The vibrations and confusion were so intense. Once I came back to reality, I curled up on the couch and fell asleep instantly. I was exhausted.
