As the wiki page says it's not yet fully understood, but I think there's a good chance it's related to how the body dissipates tension as you fall asleep - it's supposed to happen gradually but every once in awhile you get that whole body jerk. Like that, but with your auditory system, or maybe just a transient stimulation of the auditory nerves.
