The study investigates the proposed link between vestibular activation and dream lucidity. In the experiment, subjects spent two consecutive nights sleeping in a hammock in the sleep lab. In all conditions the subject was awakened after ten minutes of REM sleep and asked to provide a mentation report. Physiological measures such as REM density and EEG power were also analyzed. These results suggest that vestibular activation during REM sleep can influence dream mentation, specifically, dream self-reflectiveness and vestibular imagery.
Evidence supports a high degree of correspondence among methods which assess dreaming frequency.
Women recalled more dreams and showed a less rapid decrease in frequency than men. We found many fewer recalled dreams in senescence. However, the reduction in recalled dreams began well before senescence. The purpose of this study was to examine raters' abilities to detect a history of sexual abuse from nightmare reports. The raters were then asked to make a judgment about whether or not each dreamer had been sexually abused.
