Walk on the Moon Lyrics

I think this could be about someone who killed someone by accident or something. Like a car accident. She's swimming in gray because she's sad and feels the shame for killing whoever she killed. I really don't know what they mean. But there's a thought. The song doesn't have nearly as many metaphors or anything, its just there isn't enough detail.
