AI-extracted from the abstract
Characteristics Observational study Pilot study Peer reviewed
Population Participants reporting REM dreams and film material
Duration 5-hour interval between reports
Key findings Dream reports showed significantly greater integration of content elements and associative sentences between first and second reports than film reports, even though the physiological condition was kept constant during the interval. This indicates that dream memories are more prone to reorganization and elaboration over time than memories of film material.

Abstract

Two reports of the same REM dream, which were collected 5 hr. apart in waking condition, were compared to two film reports, collected under the same conditions. Differences in the addition of content elements and associative sentences between first and second reports of the dream and film materials were analyzed. Keeping the physiological condition constant during the interval between the two reports, the integration of content elements and associative sentences was significantly greater for dream reports than for film reports.
