With a moderate dose, you tend to be introspective and consider your own life and relationships in different ways. There’s usually a lesson at the end.
With higher doses, it’s sometimes been just extremely confusing and not at all fun, to the extent that I’d forget my own name or what I’ve taken and basically just all memories. It’s very frustrating to be in that state, constantly trying not to fly away but not able to ground yourself. It’s a little disturbing, but not horrific. I think the reason for this is that I am afraid to lose my ego/die and I would actually benefit from a slightly higher dose to blast it away...
With really high doses though, it’s been a truly beautiful, enlightening experience. I still think of it sometimes. It’s very difficult to really explain in words, but it feels like kind of extreme empathy with all life. Buddhists would call it going egoless. I just felt very at peace: we all live, we all die, and it’s all okay. I’m not particularly religious or spiritual at all but that experience really changed me. It feels like life is in all these different forms, and you just happen to be one variation of it, but you could easily be any other living thing, so you just feel love and empathy for all life. And you know it’s finite and you’re not afraid of death. I would still attempt to avoid death, but I was just at peace with it if it was inevitable. Also, when you come back to reality you’re utterly, utterly convinced that you’ve experienced something profound, possibly, despite all your rationality, there’s a message form god inside this mushroom. It’s almost like the mushroom is laughing at you: “good luck going back to your normal life now.” You’re left with “wow? That was that?!” It’s annoying honestly, because I’m not religious at all and I know it sounds crazy to even say that out loud. Of course, that feeling does slowly fade away like a distance dream or memory.
A great story it reminds me of is “The Egg” by Andy Weir:
