Sleep data were obtained on 12 well-adjusted and 11 less-adjusted Holocaust survivors and on 10 control subjects. Each was also awakened from rapid eye movement sleep for dream recall. The less-adjusted survivors had more prolonged sleep latency than the well-adjusted and the control groups and lower sleep efficiency than the control subjects. The well-adjusted group had a significantly lower dream recall rate (33.7%) than the less-adjusted (50.5%) and control groups (80%). There were also significant between-groups differences in dream structure and dream content, in the direction of less complex and less salient dreams in the well-adjusted survivors. It is suggested that the decrease in dream recall is one of the forms of long-term adjustment to severe traumatic events.
研究获取了12名适应良好和11名适应较差的大屠杀幸存者以及10名对照者的睡眠数据。每位参与者还在快速眼动睡眠阶段被唤醒以进行梦境回忆。适应较差的幸存者比适应良好的幸存者和对照组有更长的入睡潜伏期,且睡眠效率低于对照组。适应良好的组梦境回忆率(33.7%)显著低于适应较差的组(50.5%)和对照组(80%)。在梦境结构和梦境内容方面,组间也存在显著差异,表现为适应良好的幸存者的梦境更不复杂、不突出。研究表明,梦境回忆减少是对严重创伤事件进行长期适应的一种形式。
