Dreams are closely associated with rapid eye movement (REM) sleep. The purpose of this study was to evaluate the reliability of dreams in predicting the presence of REM sleep during naps of the multiple sleep latency test (MSLT). We prospectively analyzed MSLTs performed in the evaluation of 44 patients with excessive daytime sleepiness. A total of 167 naps were studied. The patients' ages ranged from 11 to 69 years (mean 45 years). There were 26 males and 18 females. The relationship between the presence of reported dreams and the presence of REM sleep was as follows: sensitivity (percentage of naps with REM in which dreams were reported), 59%; specificity (percentage of naps without REM in which no dreams were reported), 63%; positive predictive value (probability that REM occurred if dreaming is present), 29%; and negative predictive value (probability that REM did not occur when no dreaming is present), 85%. In the daytime naps of the MSLT, the presence of reported dreaming did not appear to be a reliable indicator of the presence of REM sleep in the preceding nap.
梦与快速眼动（REM）睡眠密切相关。本研究的目的是评估在多次睡眠潜伏期试验（MSLT）的小睡期间，梦在预测REM睡眠存在方面的可靠性。我们前瞻性地分析了对44例日间过度嗜睡患者进行评估时所做的MSLT。共研究了167次小睡。患者年龄在11至69岁之间（平均45岁）。其中男性26例，女性18例。报告有梦与存在REM睡眠之间的关系如下：敏感度（报告有梦的REM小睡的百分比）为59%；特异度（无REM且未报告有梦的小睡的百分比）为63%；阳性预测值（做梦时出现REM的概率）为29%；阴性预测值（未做梦时未出现REM的概率）为85%。在MSLT的日间小睡中，报告有梦似乎并不是前一次小睡中存在REM睡眠的可靠指标。
