I see this song as very different in meaning from the other interpretations I read in here. It's not a song to an old flame, or to somebody she's "snooping" on. I think it's much simpler than that. She has crossed paths with somebody, she is interested in them. They have met casually or perhaps just accidentally and for long enough that she has the other person's number and has been invited to call. But she is reluctant. Why? I think it's because she is healing from a previous relationship and is wondering if it's been long enough to "get back out there". That isn't spelled out in the lyrics, but the description of the opening scene, where she's hanging around by herself in some diner or restaurant that is closing makes it sound like she is on her own, and stays until closing because she has nowhere in particular to go. And when it says "roused my dreams again", it's not referring to the other person being an old flame. Rather, this new person is rousing those feelings of attraction in her that she hasn't felt since her last break-up.
