Dreaming that you are having a dream (a dream within a dream) - can mean you feel you're getting a higher perspective or deeper understanding of whatever it is you're dreaming about. It can also be a realization that you are dreaming (having a lucid dream), or it can indicate confusion about what is real and what is not. The dream within a dream can also represent a story that you are choosing to create or make up on the fly - just as a "play within a play" is a story that the characters are creating.
