The pain of dreams

Have you ever had that feeling after a dream:  It feels so real and you can't keep reality from dream for a moment. Then you realize that it was a dream and you know it will never be real. Sometimes it is good when it isn't real because you don't want bad dreams to be real but you still feel the fear when you wake up. Then there are happy dreams for what you nothing wish harder than it to be real. Imagine you are with a guy in your dream and that what is between you feels so real that you still feel it when you wake up and than it hits you that it isn't real.
