ABSTRACT Three adult females were awakened from EEG stage 1 REM and stage 2 of sleep and instructed to guess the stage of sleep from which they had been aroused. One subject obtained 27 correct discriminations (guesses) out of 29 awakenings after 84 training trials (awakenings). A second subject gave no indication of learning the discrimination in 65 trials; a third discriminated the two sleep stages significantly better than chance in 138 trials. It was suggested that the first subject successfully formed a stage 1 REM/2 concept that matched the occurrence of the sleep stages better than did the concept dreaming . Several problems in concept formation of internal states during sleep were discussed.
