Paraphrase : I see best when my eyes are closed. All day I am forced to look on what I do not care about; only at night, when my dreaming eyes see you, do I truly see. For even your image (ie, shadow) brightens all the shadows of a dream, and how much brighter you are in daylight, when you may be seen in reality? How much, then, would it delight me to see you in reality, when already your image in my dreams makes them so bright? Until I can see you again, my days are as dark as night because of your absence, and my nights as bright as day because of your sight in my dreams.
