Abstract
The widespread use of standard polysomnographic (PSG) criteria for identifying sleep stages (Rechtschaffen and Kales 1968) has helped promote an artificially categorical view of sleep and the unproven notion that sleep stages are mutually exclusive states separated by abrupt transitions. Rather, evidence suggests that sleep stages consist of fluid, dissociable clusters of processes, with overlaps and admixtures being common under various circumstances (Nielsen 2000b; Himanen and Hasan 2000). This emerging, alternative view of sleep has important ramifications for theories of dreaming—and thus for theories of dream function like the protoconsciousness (ProtoCs) theory.
