I saw this commercial for a wicked movie, and then I dreamnt I was in it?

On teletoon I saw a commercial for Scooby Doo 3 or something (where there all in high school), and I dreamnt my cl was in a white room with the movie playing on one of the walls. Then everyone left, but I stayed behind and then I was in the movie. Then in my dream, I ran outside and my mama, gramma, and couzin Kaitlin picked me up. Then I woke up. What do yhall think it means?
