Daydreaming styles and nocturnal dreaming.

College students were administered the Imaginal Processes Inventory and were asked to record their nocturnal dreams in a diary. The dreams of students selected as representing extremely different styles of waking fantasy according to the Imaginal Processes Inventory were analyzed with regard to bizarreness, emotionality, emotional polarity, and variety of content. Significant differences in the dream structure were found among subjects of differing daydream styles. Findings support the psychological significance of the concept of daydreaming styles and suggest parameters of cognition that transcend state of consciousness.
