A comparison might be (for me at least) mushrooms is akin to going to an art gallery, and 5-meo is like going very deep (instantly) into a sensory-deprivation flotation tank.
An art gallery in the sense that there's a lot going on, there's a lot to interpret and you're very aware of the things that are around you. Those things have a strong ability to move you, provide insight, "downloads", intepretations. It can also be (not necessarily) very social as well. It's not a perfect metaphor because it doesn't capture all the other ways mushrooms can influence you, but for the sake of this analogy haha.
A flotation tank because… well for me everything ceased to exist. There was no time, no self, no light, no thought, no sensations. Nothing. Just an experience that merged with darkness and then there was simply just an awareness. I remember "being" in a place of complete darkness (darkness isn't even the right word because it's beyond the idea of darkness even existing). Beyond concepts and words and thoughts. And the darkness was truly "beautiful". It felt like it was silently humming, vibrating even. It felt primordial, as if it was pregnant with all possible creation. And yet utterly void.
Truly a surreal experience and not at ALL the same thing!
