关于梦与特定的快速眼动(REM)睡眠机制之间存在严格关系的假设是有争议的。许多研究人员最近否认了这种关系，但他们的研究中没有一项同时控制非快速眼动(NREM)和快速眼动(REM)睡眠觉醒之前的睡眠长度和深度，这是因为NREM-REM睡眠周期的自然严格顺序。未能在觉醒前控制睡眠的长度和深度，混淆了对快速眼动与梦境关系的理解。根据最近关于快速眼动睡眠对认知功能的专一性的发现，我们假设在快速眼动睡眠和非快速眼动睡眠中做梦的生理机制不同。使用睡眠中断技术，我们从13名正常受试者中诱导出睡眠开始REM期(SOREMP)，以收集没有上述混淆的SOREMP和睡眠开始NREM(NREMP)梦。回归分析表明，SOREMP梦的发生与REM睡眠时间显著相关，而NREMP梦的发生与从NREM睡眠中唤醒有关。使用梦境属性量表评估的梦境属性显示，SOREMP和NREMP梦境报告之间存在质的差异。这些结果支持了我们的假设，我们得出的结论是，尽管像之前的研究人员所说的那样，“做梦”可能发生在REM和NREM时期，但从这两个不同时期获得的梦在数量和质量方面都有很大的不同，很可能是由不同的机制产生的。
The hypothesis that there is a strict relationship between dreams and a specific rapid eye movement (REM) sleep mechanism is controversial. Many researchers have recently denied this relationship, yet none of their studies have simultaneously controlled both sleep length and depth prior to non‐REM (NREM) and REM sleep awakenings, due to the natural rigid order of the NREM–REM sleep cycle. The failure to control sleep length and depth prior to arousal has confounded interpretations of the REM‐dreams relationship. We have hypothesised that different physiological mechanisms underlie dreaming during REM and NREM sleep, based on recent findings concerning the specificity of REM sleep for cognitive function. Using the Sleep Interruption Technique, we elicited sleep onset REM periods (SOREMP) from 13 normal subjects to collect SOREMP and sleep onset NREM (NREMP) dreams without the confounds described above. Regression analyses showed that SOREMP dream occurrences were significantly related to the amount of REM sleep, while NREMP dream occurrences were related to arousals from NREM sleep. Dream properties evaluated using the Dream Property Scale showed qualitative differences between SOREMP and NREMP dream reports. These results support our hypothesis and we have concluded that although ‘dreaming’ may occur during both REM and NREM periods as previous researchers have suggested, the dreams obtained from these distinct periods differ significantly in their quantitative and qualitative aspects and are likely to be produced by different mechanisms.
