I would say that is perfectly normal. I have had dreams after movies, television, video games, songs and books (and most my dreams are weird anyway). They are all things that stimulate the mind. I often put together a mental picture of events as I am reading them, and that has caused several dreams. I spent many nights flying around with Eric Northman after reading the first books in the Sookie Stackhouse Series, and in between the first and second season of the show. The television characters were in my mind, doing things from the books. I loved it. You're mind is meant to explore at times when your body rests, and often it recalls your activities just before bed.
When I hear terms like "hipster" I think, who told cliques they could leave high school??
