2019冠状病毒病大流行带来的当前全球威胁导致广泛的社会孤立，对应对与社交距离有关的金属痛苦以及快速学习旨在预防传染的新社交习惯提出了新的挑战。神经科学和心理学都认为，做梦有助于人们科普负面情绪，并从经验中学习，但做梦能有效地揭示精神痛苦和社会行为的变化吗？为了解决这个问题，我们应用自然语言处理工具研究了67名个人的239份梦境报告，这些报告要么是在2019冠状病毒病爆发之前，要么是在2020年3月和4月期间，当时世界卫生组织宣布大流行后巴西实施封锁。大流行病的梦显示出更高比例的愤怒和悲伤的话，以及更高的平均语义相似性的术语“污染”和“清洁”。这些特征似乎与社会隔离相关的精神痛苦有关，因为它们解释了与社会化相关的PANSS阴性子量表中40%的方差（p = 0.0088）。这些结果证实了流行病的梦反映了精神痛苦，对传染病的恐惧，以及直接影响社会化的日常习惯的重要变化。
The current global threat brought on by the Covid-19 pandemic has led to widespread social isolation, posing new challenges in dealing with metal suffering related to social distancing, and in quickly learning new social habits intended to prevent contagion. Neuroscience and psychology agree that dreaming helps people to cope with negative emotions and to learn from experience, but can dreaming effectively reveal mental suffering and changes in social behavior? To address this question, we applied natural language processing tools to study 239 dream reports by 67 individuals, made either before the Covid-19 outbreak or during the months of March and April, 2020, when lockdown was imposed in Brazil following the WHO’s declaration of the pandemic. Pandemic dreams showed a higher proportion of anger and sadness words, and higher average semantic similarities to the terms “contamination” and “cleanness”. These features seem to be associated with mental suffering linked to social isolation, as they explained 40% of the variance in the PANSS negative subscale related to socialization (p = 0.0088). These results corroborate the hypothesis that pandemic dreams reflect mental suffering, fear of contagion, and important changes in daily habits that directly impact socialization.
