DMT takes the cake. Easy.
I have experienced DMT many times and every time is much stranger than the last. Some times Ive experienced contact with alien life forms, sometimes machine like organisms. Always present seems to be these elves or gnomes. These small beings that inhabit the DMT world, they welcome you back every time you take DMT .Its a feeling of overwhelming joy and happiness that seems to take off where you last left it from your previous trip.
The most intense experience however was the time I did the most at once. Im not exactly sure how much I took as i didnt own an accurate enough scale but it was twice what I did before. When I first inhaled it I saw a bright flash of light and a chrysanthemum pattern exploding before me.It felt like being shot through a cannon through this. And then suddenly I was in Ancient Egypt. and i mean like it felt like i was really really there in the flesh and blood. There were bizarre patterns flashing all around me. about a week later I saw the symbol online for the first time. I had assumed it was just something I thought up, oddly enough it was the shamanic symbol for the jaguar, the animal representing the link to the spirit world While in Egypt I recall looking around and seeing the desert and pyramids all around me and then suddenly I was being greated by the egyptian high priest. And it felt like being in the presence of a deity.
Then all of a sudden it was starting to wear off, but , i hadnt consumed all the DMT, so I finished it, and instantly it was being like fired out of a cannon to the sky.
I remember thinking that I was on my way to heaven. Here is a good point to note that while most drugs change the way you think, DMT does not, you think exactly the same as you do sober, and you forget you took a drug, so imagine me , an atheist on my way to heaven lol. It was an interesting feeling. I remember being greeted upon arrival by thousands of beings, they felt like the gnomes, but I could not actually see them, there was just this overwhelming feeling of joy and happiness and just welcome back. I remember again being in the presence of a deity, it felt like being before god. God was a woman with long flowing brown hair, she told me her name but I cant remember it, just that it began with an E. Then as I asked her name again everything once again began to fade away and I slipped back once more to reality.
From start to finish this whole thing took place in 4 minutes lol. yet it felt like a lifetime
