I'm on a Pyramid, Chased by Cacti, and I Fall Off

I'm navigating one face of a massive pyramid, which is very difficult, because it's hard to walk around on this kind of surface. Cacti of some animate, mobile variety are rolling after me up the sides of the pyramid, and I'm very disinclined to deal with that. So I'm running away, and I forget that it's a pyramid, and I pitch off one of the corners and roll down the side of the pyramid for a very long time. I wake up amused, because of the geometric inevitability of something like this happening. c. 2012
