Dream recall frequency and nightmare frequency in patients with sleep-disordered breathing

Abstract

Question of the study There are conflicting findings regarding dream recall frequency (DRF) in patients with sleep-disordered breathing: Various studies have reported less, equal, or higher DRF in comparison with healthy controls. Although more negatively toned dreams were found in these patients, nightmare frequency had not been found to be increased in a previous study. This study concerned whether DRF or nightmare frequency was altered in patients with sleep-disordered breathing without other comorbid diagnoses and whether disorder-related parameters, comorbidity, or drug intake was associated with DRF and nightmare frequency.
