What's wrong with my subconscious?

I dreamed that I was at a Beck concert. There was an intermission, and these staff people were going around the auditorium where the concert was being held and asking people to volunteer. Apparently, Beck wanted to have a bunch of people from the audience come on stage and sing the chorus of a song. I was one of the people chosen, and so I went backstage with the others. It was really bizarre and like a spaceship; everything made of metal and plastic with no windows and lots of sliding automatic doors and the like. Somehow, some of us got separated from the main group and ended up wandering around; the place was huge. After some events which I cannot recall specifically, we realized that it was all a plot to convert us to Scientology.
