Yeah, in my dream people were being arrested for very minor offenses simply as an excuse to have them used as entertainment fodder in the arenas. That was the scary part of it, being in the middle of such a brutal and violent civilization and wondering when you might get dragged away by the authorities for some simple and stupid mistake. But even in the dream, was so fascinated by everything I was seeing, and upon waking in wonder at my minds ability to create ancient Rome in such vivid detail. Even down to the details of the clothing people were wearing, and the sandals on their feet. ( I guess based on what I've seen in movies and TV.)
You should watch the movie at least if you have the chance, I'm not sure if it's on Netflix or not. I have it on DVD. The last time I watched it was something like four years ago. I should watch it again one of these days on the theater screen inside my VR headset. :)
