I would say the experience would be closer to peyote out of the three. We produce it naturally in our pineal gland from what I understand, during birth and death. It only lasted for maybe 6 minutes in my case, but it was super intense.
The first thing that happened was I heard a noise. Started off like a low humming but got insanely loud. Sounded like a jet engine by the time It fully came on. Then there was this being. It's body reminded me of what a 'grey alien' would look like, Big head, huge eyes, small thin body. Except it has wings like a moth that more undulated than flapped. It was also a pulsing and constantly changing neon spectrum in colour. There were green mandala like patterns and spirals coming off of the tips of its wings. It just kind of hovered there looking at me with it's head tilted to the side. It seemed benevolent, but I got the sense it could destroy me without breaking a sweat.
Needless to say I was scared shitless, and remember worrying that I was going to be permanently stuck in the trip. Then it faded away, and the rocks around me took on an appearance of reptile skin. I could clearly see numbers in the rocks/skin...3,7,5,17,23,32,42,72. Also symbols/siguls, some looked familiar, but I haven't figured out from where yet. Then that faded as well, and the jet engine noise dulled to a hum and finally faded into the babbling of the river I was sitting next to.
Then I crawled over to my backpack and proceeded to try and drink whiskey and beer while loading a bowl and lighting up a cigarette. It shook me up pretty good.
I'll try and find the passage in the book I've been skimming and post it. It's fucking freaky how many people report seeing the same things that I have.
