To me, the real focus of this song isn't on the person he is talking to; rather, its the message he's getting across. In a nutshell, I think he's relating that people think themselves silly struggling to find and/or apply meaning and reason to everything, and he's using the situation described in the song to get this across. Sometimes, we just don't need to think so much (go to sleep), and instead maybe relax a little and enjoy life because we never really know anything for sure.
