It happens to me with movies. I saw one with this guy who looked just like someone from my dreams. In the movie, he was singing and dancing. Which was so weird because in my dreams, he works for the FBI and he's the last person that would burst out into a musical number.
And in one of the Star Wars movies, there's a guy that looks just like someone else from my dreams. Which is also very strange. My dreams aren't the sci-fi type either.
