The COVID-19 pandemic has been a collective trauma for the world population. Psychoanalytic literature has long proposed that dreams are a key point of access for understanding the deepest functioning of the mind. Using the multiple code theory (Bucci, 1993) as a framework, this study aims to explore the emotional and cognitive responses of the general population to COVID-19 through their dreams. A total of 613 dreams were collected in an online survey. Linguistic measures of referential process and a cluster analysis were performed, then one-way analyses of variance explored the differences in content among dreams' clusters according to the Linguistic Inquiry and Word Count (LIWC). Analysis suggested three dream clusters: Cluster A (N = 255) defines an arousal activation; Cluster B (N = 121) defines a phase of symbolization; Cluster C (N = 237) defines a phase of reflection/reorganization. The content analysis of LIWC presents significant differences among the three clusters (p < .05): Cluster A, compared to Cluster C, included less use of the term "we," more frequent reference to others, and more frequent use of words denoting certainty; Cluster B included more words of negation and more use of both the present tense and the verb "to have"; Cluster C included less use of words referring to wishes and illusions. These results show differentiated functions of dreams in response to the pandemic experience, underlining the importance of dreams in the processing of this collective trauma. 2019年冠状病毒大流行(COVID-19)可以被认为是一种普遍的集体创伤。精神分析文献认为梦是理解心灵最深层次功能的关键。考虑到多重代码理论,本研究旨在通过梦来探索普通人群对COVID-19大流行的情感和认知反应。在线调查共收集了613个梦。对参照过程(RP)进行了语言测量和群集分析,以及单向ANOVAs,其根据语言查询和单词计数(LIWC)探索了梦境集群之间的内容差异。根据分析,从数据中出现了三个梦的集群:集群A(N = 255)定义了唤醒激活;集群B(N = 121)定义了象征阶段;集群C(N = 237) 定义了思考/重组的阶段。LIWC的内容分析在三个组别之间呈现出显著差异(p<.05):与组C相比,组A较少使用"我们",更多地使用"他人"和确定性词语;B组梦更多使用否定词、现在时使用和动词"有";组C较少使用提及愿望和幻想的词语。这些结果显示了梦在应对大流行体验方面的差异化功能,因此强调了梦在处理这种集体创伤方面的重要性。
