Both patients with narcolepsy and insomnia frequently present clinically with nocturnal sleep disrupted by disturbing dreams. Polysomnographic correlates of these reports are unclear. In this study, 24 patients with psychophysiological insomnia and 16 patients with narcolepsy were compared on selected polysomnographic and self-reported typical dream characteristics. As a group, patients with narcolepsy showed more frightening, recurrent dreams and shorter rapid eye movement (REM) segments when compared with patients with insomnia. However, within the narcolepsy group, there were few correlations between typical dream characteristics and any measure of REM segment length or REM density. In the insomnia group, shorter REM segments and higher REM density were related to typically more vivid, frightening, and disrupted dreaming. We speculate that the mechanisms of disturbed dream recall may be different in insomnia and narcolepsy.
发作性睡病患者和失眠患者临床上常常表现出夜间睡眠被令人不安的梦境打断。这些报告在多导睡眠图方面的相关性尚不清楚。在本研究中，对24名心理生理性失眠患者和16名发作性睡病患者的多导睡眠图及自我报告的典型梦境特征进行了比较。与失眠患者相比，发作性睡病患者总体上表现出更多令人恐惧的反复出现的梦境以及更短的快速眼动（REM）时段。然而，在发作性睡病组中，典型梦境特征与REM时段长度或REM密度的任何测量指标之间几乎没有相关性。在失眠组中，较短的REM时段和较高的REM密度与通常更生动、令人恐惧且被打断的梦境有关。我们推测，失眠和发作性睡病中梦境回忆受干扰的机制可能不同。
