A lucid dream is a dream in which one is conscious of dreaming and can possibly control the dream or passively observe its unfolding. Frequencies of lucid dreaming (LD), dream with awareness, and dream with actual control were previously investigated in a French student population. As a student population usually differs on oneiric and sleep characteristics (such as sleep quality) from the general population, more investigations were needed. Additionally, it is yet unresolved if LD is related to one's overall sleep quality. This study aims at describing and comparing dream experience frequencies (dream, lucid dreams, awareness, and control) and sleep quality assessed with the Pittsburgh Sleep Quality Index (PSQI) among students ( = 274) and in a general population sample ( = 681). It also aims at evaluating if dream experience frequencies can predict sleep quality across these two samples. Predictive models of PSQI score controlling for age and gender were not significant in the student group while they were all marginally predictive for the general population. However, none of these models showed that the frequency of dream experiences could actually help predict the quality of sleep as the significance of the model was carried over only by the gender variable. These results are discussed in line with previous studies on LD frequencies. Several methodological adjustments for future study are proposed.
清醒梦是指人在做梦时意识到自己在做梦，并且有可能控制梦境或被动地观察梦境的展开。之前在法国学生群体中对清醒梦（LD）、有意识的梦以及有实际控制权的梦的发生频率进行了调查。由于学生群体在梦和睡眠特征（如睡眠质量）方面通常与普通人群不同，因此需要更多的调查。此外，清醒梦是否与一个人的整体睡眠质量相关仍未得到解决。本研究旨在描述和比较学生组（n = 274）和普通人群样本（n = 681）中梦的体验频率（梦、清醒梦、有意识状态和控制权）以及用匹兹堡睡眠质量指数（PSQI）评估的睡眠质量。它还旨在评估梦的体验频率是否可以预测这两个样本中的睡眠质量。在学生组中，控制年龄和性别的PSQI得分预测模型不显著，而在普通人群中它们都具有一定的预测性。然而，这些模型都没有表明梦的体验频率实际上有助于预测睡眠质量，因为模型的显著性仅由性别变量决定。结合之前关于清醒梦频率的研究对这些结果进行了讨论。并为未来的研究提出了一些方法上的调整建议。
