Hello, "Rob4580"...
Over the years, everytime the song, "Beautiful Dreamer" has reached my ears, it almost always was presented in the context of a parody that mocked romantic sentiments, usually in television shows and commercials. I 'm sure its archaic language had something to do with the disrespectful treatment it has received. This is the first time I've heard it sung in its entirety with all of the lyrics intact.
That being said, the way you sing it, "Rob4580", does indeed impart the quality of a dream. I could imagine you crooning the song to win someone's heart on a clear, cloudless night dominated by a big, brilliant moon.
I could use some insight into the what is the subject of the song, though

!!! Nonetheless, the melody is unforgettable and you wrap your voice around it with all the tenderness of a lover's caress.
For all beautiful dreamers,
LOREN
