Abstract

We investigated the relationship between length and dreamlike quality in sleep mentation reports. Reports were obtained by waking subjects at sleep onset (SO) and at 5 and 10 minutes into the second (REMP2) and fourth REM periods (REMP4). Reports were recorded, transcribed, and scored blindly for total word count (TWC) and dreamlike quality as measured by a composite dream scale score (CDS). Dreamlike quality was strongly correlated with TWC; both CDS and TWC scores increased across successively later awakenings. Significant differences were found in both TWC and CDS between SO and REMP4 and also between REMP2 and REMP4; however, differences were not significant between SO and REMP2 or between the 5 and 10 minute awakenings in REMPs 2 and 4. These findings provide further evidence that the amount of dreamlike mentation is related to the within-sleep arousal level rather than to REMP duration and that the dreamlike quality of reports increases as they become longer.

摘要

我们研究了睡眠思维报告中长度与梦境般特质之间的关系。通过在睡眠开始（SO）时以及进入第二个快速眼动期（REMP2）和第四个快速眼动期（REMP4）的5分钟和10分钟时唤醒受试者来获取报告。对报告进行记录、转录，并由不知情的人员对总字数（TWC）以及通过综合梦境量表评分（CDS）衡量的梦境般特质进行评分。梦境般特质与TWC密切相关；随着唤醒时间越来越晚，CDS和TWC评分均升高。在SO和REMP4之间以及REMP2和REMP4之间，TWC和CDS均存在显著差异；然而，SO和REMP2之间或REMP2和REMP4中5分钟与10分钟唤醒之间的差异并不显著。这些发现进一步证明，梦境般思维的数量与睡眠中的唤醒水平有关，而非与快速眼动期持续时间有关，并且报告的梦境般特质会随着报告变长而增加。
