I think it says a lot about the underlying qualities of the psychedelic experiences if we commonly and reliably can experience visuals similar to this.
Fractals are are ubiquitous in nature (clouds, plants, galaxies, shells and more), since nature will always follow the simplest and most efficient path. Fractals are maps of the simplest paths sliding up the scale of dimensions. Perhaps its simply an artifact of nature's elegance that we find exact correspondences between these inherently existing mathematical forms and natural patterns, and even living creatures of many types, and of course the psychedelic experience.
Certainly as far as im concerned this correlation of fractals, nature and psychedelics, gives credence to my inclination to engage with psychedelics. As in, we're supposed to be tripping!
