It's interesting to learn that there is significant doubt about the connection between DMT and dreams. I apologize if I sounded snobby. Truth be told, I just assumed I would be one of the least advanced/experienced people here, and therefore I was not even considering the possibility that people who think sex is the best thing ever and death the worst thing ever might be reading my post.
I can't really report much, because I haven't had much of an experience. Just barely enough to recognize the moment-to-moment nature of existence, to recognize that any real thing that I thought was "I" is fundamentally the same as any other real thing, and that's just about it. The "trippy" experiences that I have were few and far between. Let me give a few examples, since you asked for it
The very first one happened in a dream. I was sitting in a big hall held up by columns, surrounded by forest. This is no place I know from real life, but I can imagine something like this exists maybe somewhere in India or Thailand. I was just trying to be very still, looking at the trees, and at the end of an out-breath, my vision started strobing. It looked just as if I were opening and closing my eyelids as fast as I could and lasted for maybe half a second. When I started breathing in again, everything was back to normal. On the next out-breath, it started again, and this time it persisted, and a breath later, I was gone. I could not see anything anymore, the only thing left was the sensation of falling/floating, slightly sideways, into a state where there was no body, just a general pleasant mental feeling. This lasted for a few seconds, and then I woke up.
The strongest one I have ever had happened when I was about to fall asleep or had just fallen asleep. A green visual appeared, not particularly intricate, but I couldn't recall its exact form afterwards. Then a loud tone started, very similar to a sawtooth wave. I found it neither pleasant nor unpleasant, but after a couple of seconds, it started to chop. It sort of fragmented into smaller and smaller pieces. Then it was gone, again I fell into a very similar state as the above, only this time it was much stronger, the mental feeling also went away, and then there was nothing. I don't know how long that lasted, but probably just a couple of seconds. As I came out of it, I heard the most beautiful music, and a few seconds after that I was totally back to normal, except I couldn't even remember a single note of that music.
Something similar happened months later, except this time I was just relaxing, not really close to falling asleep, when it started happening. Again all hearing and seeing stopped for a few seconds, but this time there was still some thinking. In particular I had the thought that this was the first time something like this has happened to me when I was definitely not asleep or falling asleep. This very thought, though, brought me right back out of it.
The most "concrete" experiences are not as pleasant and don't feel as useful. They usually revolve around the theme that, on occasion, I will be able to close my eyes and see—not just imagine, but actually see—some pattern, and most of the time, I can influence the pattern by thinking. One time, when I had a really solid experience of this nature. I couldn't just subtly change the patterns, but I could cause pretty much anything I wanted to appear, so I thought it might be interesting (and possibly quite beautiful) to create the image of a naked woman. So I did, and it worked for a second or two, but then the whole thing ended.
The only experience that somewhat resembles hyperspace as you guys seem to be describing was what happened to me when I was hypnotized. I wanted to be hypnotized just for fun. I didn't know anything about it at the time, but trusted the woman who did it. She never told me this, but what she actually did with me was an attempt at past life regression. Instead of a human past life, I suddenly found myself floating in a huge, black space with purple and orange blobs of light. They were alive, and I was one of them. Their shape was simple and blurry, but the colors were very intense, even though only those two colors existed, with the exception of the light that was myself. I was green and blue with a more complicated pattern, not really something I could draw, though. To be more precise, I wasn't actually that thing itself, but it felt sort of like I was a disembodied mind looking at its body, and that body was the green/blue blob. The other lights (the purple and orange ones) seemed like they were trying to guide me. They felt very benevolent, but actual communication did not happen.
That's about it. As you can see, my experience compares to yours like walking around my house would compare to flying overseas. The point is, though, I have left the house and know that there is a much bigger "real world" out there than I could have ever imagined. This forum is my way of finding out about it.
My original post was meant to be read in this context: I am someone who knows that what you guys experience is real. It interests me more than the so-called real world, but at the same time I know next to nothing about it.
