I guess reality, to me, means something stable something you can fall back on. Reality has a good set of rules. Reality is defined by constants. I think I'm getting a grip on things. I don't even remember how I'm supposed to act anymore.
Nothing is real.
Neither you nor I nor anything else in this world is real. No I didn't. But there are certain differences between dodecahedrons and circles. A circle is quite different, as it is not a polygon. I'm sorry, but I don't understand what you mean.
