In a 1987 interview with Karl Dallas in the book, Pink Floyd: Bricks in the Wall, the songwriter and bassist for this track, Roger Waters commented on the meaning behind the final two lines on the verse of “Eclipse.”

I don’t see it as a riddle. The album uses the sun and the moon as symbols; the light and the dark; the good and the bad; the life force as opposed to the death force. I think it’s a very simple statement saying that all the good things life can offer are there for us to grasp, but that the influence of some dark force in our natures prevents us from seizing them. The song addresses the listener and says that if you, the listener, are affected by that force, and if that force is a worry to you, well I feel exactly the same too. The line ‘I’ll see you on the dark side of the moon’ is me speaking to the listener, saying, ‘I know you have these bad feelings and impulses because I do too, and one of the ways I can make direct contact with you is to share with you the fact that I feel bad sometimes.
