Whats a high dose of DOM to you? Personally I don't know quite what what you mean by mind expanding, could you explain that specific quality in more detail? I for one have not found a hallucinogen or any drug with more powerful influence over my mental state, and I've done a reasonable variety of them. Not only that, nothing even came close to the visual symphony I would get with DOM. I clearly remember that when on 20 mg, the visuals were so intense that I could barely discern the between the background image and my friend standing 10-15 feet away. The only reason I knew he was there was because of the white/gray plaid pattern on his hoodie, he was nothing but a small portion of floating hoodie. If I looked at the same spot for a bit, the depth perception disappeared completely and it looked like i was living in a photograph of reality, that was ridiculously distorted in almost strictly vertical and horizontal lines. Not only that but red and purple hues seemed to appear in everything. It was two in the morning and the auditory hallucinations made it seem like i was standing next to a freeway, next to planes taking off, and that every light buzzed intensely. In a negative sense, I also felt methed out. It was weird to watch people move because it seemed like my eyes would drop frames, so any quick minor displacements resulted in what looked like instantaneous travel. Cats for example, which seem to only move that way, are absolutely intense, their meows, their walk, everything. Large displacement result in discrete trails where I would see a perfect series of images instead of a smooth blur. Everything also appeared to take on a satin like wet appearance, which would at first appear on all surfaces, but like I said, looking at the same spot kind of just caused the image to glaze over in 2D, appearing picture like. As for mental effects, I'll go into that later. But I don't see how you can consider DOM to not be a true psychedelic with those sorts of effects. Maybe it just doesn't work for you, but for me, its a deep down and dirty feeling trip that so far remains unapproached in intensity by other things.
