Narrative: Case study 27.1 summary
A sample of undergraduate psychology students were randomly divided into three groups and asked about their experiences with acting out dreams while dreaming.Group 1 was asked "On how many nights did the following occur in the last year … acting out a dream (while dreaming) ?" Group 2 was asked the same question as Group 1, but with some examples given of "acting out a dream while dreaming", such as crying, laughing, making arm/ leg movements.Group 3 was given a specific list of dream-state actions and asked which of these they had experienced.That is, the subjects in Group 3 did not need to synthesize their own interpretation of the phrase "acting out a dream" or conceive of their own example actions.The proportions of positive responses for Groups 1, 2, and 3 were 35.9%, 76.7%, and 98.2%, respectively.
