I ended up reading all of Einstein's Dreams on a single bus ride to Boston. The inside of the bus was normal and boring. Periodically, I would take a break from reading and look out of my window. I began to see the outside differently. The trees by the road side moved from right to left. And then sometimes left to right. Sometimes the trees began to stop completely. I was struck by how mind altering these stories could be in that they would change my perspective on the external world.
The interludes showed an Einstein that I did not expect. A quiet person who full of many ideas. He also seemed a bit sad, perhaps knowing that he is unable to experience any of these universes with a different mode of time. I took a short nap after the second interlude. I did not dream.
As I continued reading, I began to think, what if time behaved differently inside every single vehicle on this highway right now, just like each version of Berne. The bus had its own set of rules inside, rules that differed from the red Mazda 3 speeding past us. I then looked over to the other side of the highway barrier. The people in each vehicle in the incoming traffic viewed the complete opposite of my current point of view. And in three days, I would be on that side experiencing the same thing when I would be coming back down to New York. When I finished the book, it was dark outside. Time had passed outside of the bus while I was inside experiencing the many Bernes of Einstein's dreams.
