"[The volume] was a little over a whisper, probably much [quieter] than ... your iPod," says John Rudoy, one of the study's authors and a graduate student at Northwestern...

The prevailing theory is that during deep sleep, the brain replays certain experiences from the day, which, in turn, strengthens the memory of what happened. It is thought that when it comes to factual memories, like names, faces, numbers or locations, memory consolidation happens only during deep sleep - a phase of non-rapid eye movement sleep.
