Dreaming in Digital

It was a new fall semester at university and I attended the first class to my ethics course. It was a massive class of about 300 students. I sat in the back with a window behind me, as the rest of the class was dark. We watched a movie and was released later. I had another class after this one, so I took an underground path. It looked a little dangerous, but after a while of walking without direction, I realized this path could take me to Waterloo (though I was already in Waterloo). I went back the way I came into the school's courtyard, which looked like my middle school's playground but with more overgrown brush. As I hurried late for my class, I wondered what other courses I had taken.
