In the Arms of Sleep

I read the majority of these comments, but I don't think anyone is seeing it as I have:

I interpret this song to be a very sweet take on the urge for the sin of "surprise sex," of taking advantage of a partner while they sleep.

The title "In the Arms of Sleep" is personifying Sleep, and expressing the narrator's jealousy that the lover has gone to be with Sleep instead.

"I'll miss her wherever she goes" refers to the lover being away in dreamland, and that missing a sleeping partner can be as lonesome as their physical absence.

The idea of "shadow moves" or ghost moves could mean that the narrator is so eagerly watching the still body, that he questions whether he actually saw the body move or not. And he "kisses" those shadow moves, probably trying to gently confirm if awake or not.

By the end of the song, the longing is too great. While expressing conflicted feelings about it, willing to beg and pray as a "saint," to "do anything" if necessary, the narrator commands the lover to "suffer" his "desire." This indicates he's given into some impulse to take advantage of the lover or at least awaken the sleeping lover. "There are some things" he can "live without," but he needs the lover "right now."

We can debate the implications of consent, but the sentiment is definitely there.

This song's themes and tone seem similar to some of the explorations of dysfunctional female relationships you'd see Corgan bare later on 'Adore.'
