An association between hypnosis and sleep has a long tradition. However, the electroencephalograph (EEG) of hypnosis reveals a waking rather than a sleep state. Nevertheless, this fascination with possible behavioral and subjective similarities between sleeping and hypnotic behavior along with our conviction that cognitive activity during sleep is richer than mere dreaming led a group of researchers to conduct the studies described in this chapter. These studies document that meaningful behavioral suggestions can be administered and responded to during sleep, without necessarily evoking arousal from sleep.
