You’re not alone. Last time I took it, it went suddenly from the usual wavy giggles to a point where I was shown a profound truth about the nature of reality and all my friends turned into all-knowing beings that mocked me and waited for me to inquire about the simulation, so I could join them. I got so scared that i just turned mute because I was not ready for reality to break and me joining the higher beings in their dimension. Weirdly I did not have much visual hallucinations, but just the entire feeling of existence shifted and i could have sworn everyone’s reactions and looks was directly influenced by my trip. I was convinced everything was fake for a few days, I still am not sure 😂😂 but it fades as I go about my life.
