The content of 166 sleep speeches uttered by 28 paid chronic sleep talkers in the laboratory was compared to the content of wakeful mentation reports elicited shortly after utterances. Concordance between the two in varying degrees was discernible in 79.2% of rapid eye movement period, 45.8% of stage II and 21.1% of stage III–IV speech report pairs. Concordance tendencies were also studied on several varying experimental conditions.
