Do dreams protect sleep? Testing the Freudian hypothesis of the function of dreams

A review of the literature indicates that a physiological function for dreaming has not yet been empirically established. Based on recent findings regarding the neural correlates of dreaming, this study tested the Freudian hypothesis that dreams protect sleep. In order to do this, sleep architecture in patients who had experienced dream loss as a result of thrombotic stroke in the region of the posterior cerebral arteries was compared with that of patients with the same pathology who had not experienced dream loss. Using medical records, structural neuro-imaging, clinical interviews, neuropsychological testing, analysis of subjective sleep quality, and polysomnographic data collected over two consecutive nights in the sleep laboratory, two non-dreaming and three dreaming cases were studied. Analysis of the individual case studies indicates that sleep was disrupted in both non-dreaming cases.
