1st time dmt experience

Tried a smaller dose that was enough to get my guide on the verge of breaking through, but ended up trying two additional times with more each time. The last time I did twice the amount of the first time maybe .035ish The trip: 4 stacked hits The first time I felt the effect it seemed like everything got brighter (my eyes were closed) and any outside stimulation seemed to activate the visuals I was having. At first it seemed like I was in a dark cave of sorts made of mostly grey and white spiral like shapes that collided and when they collided I was seeing purple metallic tentacles of light throbbing. Then I had the sensation that a curtain was gently rustling in a breeze hiding the true contents of the cave. I heard what I believe was "my mind" saying, "they are laughing at you." And immediately after the thought something said to me,"who is they? And who cares?" The curtain would occasionally sway and behind the curtain I would see an emerald aura energy being and an abundance of colors and lights would peak through momentarily. Shortly after, my awareness of the physical world came back and I sat there trying to process what I saw/heard and whether I needed another larger dose. The second entrance was maybe 15 or 20 min later and I took .035ish again and stacked 5 hits instead of 4. This time I was in a place I didnt comprehend. I was seeing the "tentacles" again but now they were neon rivers of rainbow. I felt like I could see the motion of the energy and traced it to its source. The emerald aura was at the center of everything, but when I could directly see the energy source it revealed itself as a man like figure (no hair, but had arms legs and torso). The rivers were flowing from him and when I looked around it was like I was being surrounded by the rivers. I heard faint whispering that I couldn't make sense of, and then the emerald man appeared twice in the gaps of the river's pattern. The first time he moved, he raised himself to the level I was and spun around gracefully. When he finished his rotation his shoulders sprouted plant like leaves, he reached out, and locked eyes with me. Almost instantly after that he appeared almost inches in front of my face with a mischevious smile. Just as quickly as he appeared he was back in his original space. Rivers flowing from him again. I asked if the place we were was his, and he looked up at me and "flexed" his energy (not muscles). When he did this all the rivers were twice as intense with movement and brightness. I took it as a sign I had disturbed him or crossed a line of some sort. He went back to what he was doing as if he also knew he had communicated with me successfully and I came back. I'm still working through what everything actually means to me, but I'm curious if anyone else has experienced anything similar.
