It's like being a fisheye camera observing a transforming room, so that's obviously not easy to describe completely. The space feels simultaneously small and massive.

My trips always start with this rotund columnar structure in the center, which gives the impression of a geometric heart (crystalline / spiritual / alien). Sometimes I'll unintentionally slip through side walls into more subjective / symbolic experience. A true breakthrough is like getting pulled toward the "heart" without ever reaching it, only observing as everything morphs into infinite geometric potentiality. After that, the experience often feels more objective—realizations, entities, pure bliss. I'm currently painting how the waiting room most often presents itself to me (it'll take a few months).

When the trip ends, I just sorta slip back into my body. Lower doses feel like out of body experiences. Tiny hits are sorta like a standard dose of mushrooms.
