Based on several other songs on this album, I'd have to say this is another reference to her trying to get over her attachment to a lost love, and that she wants her current love to be patient just a little while longer - because while this process has been like running a maze like a rat in a cage, her cries of anguish are getting quieter and quieter, and are in fact, right now, down to a whisper. And soon the past love will be like nothing but a daydream she once had.
