There really isn't anything quite like it, and I looked. I get the dissociated aspect too, and it often made me feel like I was on some kind of alien spaceship made with ancient technology but modern technicolor. The color combinations had some resemblance to 2C-B and 2C-C but not as much as they do to each other, and there was a lot going on with 2C-I that still hasn't been present in those for me. The flowery geometry in particular still really stands out in my memory. It was also good for bizarre synesthesia, like one time I saw the right and left sides of the room growing big and small opposite to one another back and forth while also hearing the right and left side of my hearing the music go loud and quiet in tandem, which was really strange to experience. Actually, the only thing I can recall being similar to that was one time on a blotter I was never able to identify, but had reason to suspect it might be DOI; I need to get around to taking that little bit of that I have....
The experiences you describe sound a lot like a type of dissociation I've become much more acquainted with as of late. I like to think of it as the reason that people like to incorporate ideas of backwards/upside down/mirror worlds in fiction.... One way I've been thinking about it is like a Möbius strip: the strip has only a single surface yet the way it's folded makes it so that you're always relatively on one side or the other at any given point, and if you consider the strip a flatland, then if you travel around the strip one time, you'll end up in the same place, but as your mirror image. Furthermore, if when you begin you already have a duplicate mirror image self, they'll end up where you started. The thing about everything being mirrored is, it may seem extremely different to what you're used to, but it has exactly as much structure as the version of it you're used to; for example, if I flip the valuation claims in the statement "This food is delicious and I love it; I would recommend everyone try it!" it becomes "This food is disgusting and I hate it; I would caution everyone avoid it!" Both are rational sentences, even though they describe completely opposite contexts. This is a concept I had to grasp recently to bring myself back from the edge of insanity, as it's impossible to trust anything when you perceive reality in two opposite ways that seem equally stable, and both supported by the things everyone says to you, even if it's that one version is telling you you're crazy while the other version is telling you you're sane.
What would life be like if we always perceived things from the other side instead? Would we still agree upon everything? It feels like it sometimes.
