Dreaming Sweet Or Sweet Dreams

Oh yes, there is a beauty in dreaming. Not dreams of the future, but the dreams that come when you see close your eyes. Wonder if there is a difference between 'sweet dreams" and "dreaming sweet". To me "sweet dreams" is just what someone says to you just to be polite before you sleep. The dreams that therefore hugged you all night are just a comfort. But "dreaming sweet" are the dreams that make you wake up with a wide friggin' smile on your face. these are not wet dreams but just dreams that just make you feel good.
