Dream of

In my dream, I was in some kind of library. There was a big window on my left side, and the sun light was very bright. I can understand it was morning. I am reading a book and find a poem in it. As I read, I realize that it is a poem that I've written. I find it very beatiful, the most beautiful poem I've ever written. Then I realize I am in a dream. I say to myself "I wish I can remember this poem when I wake up". But i couldn't remember it when I wake up.
