I once dreamed that I was in an X-Files episode. I was The Person Who Is Going to Die Before Scully And Mulder Get There. In the dream, the monster of the week showed up at my door, and I tried to run away, but I knew I was doomed, because I was The Expendable Extra. As the monster caught me, I saw that Mulder and Scully were even now pulling up outside the apartment building, but it was too late.

It was a lot more fun the time I dreamed that I was Scully, because in that dream, I knew I was the heroine of the series and thus couldn't die.
