I was studying really hard for my qualifier exams in my PhD program. Before my qualifier, I had dropped by my international business professor's office to discuss his portion of the exam. He was super vague, no useful clues at all. Usually, they give you some guidance. You have to memorize the contents or themes of the relevant papers, the authors and years. It is good to have some kind of limitations. I got the idea that maybe he wasn't that sure what he would ask.I dropped by a little closer to the date of the exam. He said to focus on the main themes of the seminar. The other professors gave me some good parameters. My stats professor was rather specific.With my IB professor, I was still confused. What were the main themes? I studied the papers, considering the themes.Then, one night, after staying up studying, I dreamed that Dr. Who came up and talked to me. I used to watch Dr. Who, a British show, when I was a teen in PBS. Every so often, the doctor 'regenerates' into a different form and the show gets a new actor, and so it was the longest running sci-fi show for a long time. I'd seen some episodes of the revived version of the show on BBCA, and the actor from the shows I'd been watching was the one I met. (David Tenant. I confirmed this with a web search.)Dr. Who told me to study internationalization.I did. I also studied other themes as well. The question my professor gave me was what is the difference between internalization and internationalization. I figure, Dr. Who could travel in the future and know what was on my test, since he is a time traveler. I suppose I could interpret this as a kind of spiritual dream. But this is one case where a psychological explanation could make sense, that my subconscious was working through this stuff.I stopped watching Dr. Who when I saw they kept putting LGBT themes in the show and promoting that kind of junk on what used to be a children's show
