I've asked myself a fair amount of these questions with the large exception of why do shrooms make me feel like a god, because the couple of times I tried shrooms they made me feel nothing like a god, I felt weird as fuck and I was tripping balls but I felt nothing like a god. I've also done plenty of other hallucinogens and none of them made me feel like a god, LSD just made me trip balls and gave me a weird body buzz that I sometimes enjoyed, AMT was the longest most abysmal trip I've ever had and a couple of other research chems that I cannot recall all the names of like 2-cb and such made me trip hard but never felt particularly good, I had a bad batch of pressed ecstasy pills that were apparently PMA and I had the most insane and vivid hallucinations of any drug I'd ever touched. To the point where my buddy morphed into Tupac holding glowing scimitars (they were actually glowsticks) and waving them around in my face, then seeing a McDonald's menu pop up in the kitchen I was sitting in, those are just two examples from that night but it was a nonstop hallucination fest, the worst of that evening was doing a whippit and basically passing out standing up and hallucinating that I was playing Mario Bros and that I died in the game and GAME OVER popped up in giant red letters and I legitimately though I had died. For years I honestly wondered if I had in fact died that night and I've been living in some kind of hell, I took 10 ecstasy pills that night and they were not even MDMA (I wasn't aware of this at the time but it was the one night I didn't research the pills we got because it was a last minute party). Never once did I feel like a god though, I just always hallucinated crazy shit, the one hallucinogen that I haven't tried that I've always wanted to is DMT, it's been years since I've touched any drug and I have zero desire to but I still want to try DMT and if it ever just landed in my lap I'd do it in a heartbeat but I probably won't ever go out looking for it.
