Will People in the Second Dimension Dream About Electronic Braised Pork?

After I picked up the car from college, there was an extra "person" in my passenger seat. He said his surname was Luo, that he loved braised pork and didn't know the way around, but would say to me when I was tired: "…you did a good job." My roommate said I was sick, but I knew he was just a figment of my imagination. But it doesn't matter, he accompanied me through the worst road in my life.
