The way those geometries move resonates with my understanding of multidimensionality. When people conceive of the fourth dimension as time, it seems uncalled for to move from spatial dimensions to temporal ones. It is logical to see why such assertions have historically been made because our default mode of consciousness only allows us to perceive three dimensions. DMT presents multidimensional geometry directly to the senses, and "basic" forms of this multidimensional geometry can be recreated by computer models by projecting the higher dimensions onto the two dimensional plane of a computer monitor. The main problem with trying to understand hyperspatial geometry through tesseracts, E8s and the like is that it is akin to trying to understand consensual reality through the study of cubes and octahedra. That is to say it is uncommon to encounter the platonic solids at the macro scale in nature just as it is unlikely to encounter a tesseract in hyperspace. In hyperspace, multidimensional geometry is used to create meaningfully or referentially in a way that I have yet to see with computer generation. Our artists need to team up with our mathematicians to see if we can truly artistically harness the multidimensional aesthetic.
So to jump back to why the fourth dimension should not be time, I also feel that time has its unique set of dimensions which seem to parallel their spatial counterparts. Zero dimensional space is a theoretical point. Zero dimensional time should be a theoretical point in time - a moment (perhaps the present moment is a good example). One dimensional space is a line segment, so I would wager that one dimensional time would be the linear progression from one point in time to another. This is the way that most people tend to think of the motion of time. Two dimensional space introduces the concept of width and polygons. I think two dimensional time would be something like how humans typically experience time - relatively. Time seems to move slower in the dentist's chair than playing one's favorite game with friends. In regards to three dimensional time, I think that this is perhaps a dimension of time that humans rarely experience similar to how we rarely perceive fourth dimensional space. On one of my strongest DMT experiences to date, I recall describing part of it as feeling as if I could literally feel the particles of time dilating like spheres (three dimensional time?) as sense of time slowly grew to a halt till I was left suspended in a sea of eternity (fourth dimensional time?). Anyway, this is just my temporal dimensional theory which I know conflicts with the popularly accepted explanations.
