two ideas:
1. that time is actually a sideways movement. that what's really going on is another direction from that. like an axis on the graph. x instead of y.

2.that dimensions are a false abstraction. I was looking down at my pants this morning, sitting on the toilet, and what I later realized I was seeing was the linoleum through a gap between my belt and my pants, but until I understood that intellectually there was no depth or no accurate depth to what I was seeing. it changed when I "understood" it. my mind changed it. the height/width/depth axes are subjective. it's really circular or global, not rectilinear.
