Talking in sleep is a related phenomenon to sleepwalking. Moorcroft (1993)
suggests that it may occur during stage 3 and may actually be a result of
intrusion of stage 2 electrical activity during stage 3 sleep. It has to
occur in NREM sleep, because in REM the motor system (and hence the speech
system) is paralyzed.
