During the COVID-19 pandemic, dreams did not become more threatening or nightmarish overall compared to before the pandemic. Analysis of 1,132 pandemic-era dreams and 166 pre-pandemic dreams found no differences in the number of threatening events, disease-related threats, or severity of threats between the two periods. However, the minority of dreams that directly referenced the pandemic did contain more threats, disease-related threats, and severe threats. The findings suggest the pandemic's impact on dream content was limited to a subset of dreams rather than causing a general increase in threatening dream content.
Individual factors, such as low life satisfaction and fewer positive emotions, are better predictors of threatening dream content during the COVID-19 pandemic than daily situational factors like worry or media consumption. In a large Finnish sample of prospective dream diaries, lower life satisfaction was the only statistically significant predictor of threatening events in dreams, while experiencing fewer positive emotions in the past two weeks was the only significant predictor of pandemic-related threatening events. The findings suggest that the tendency to have threatening dreams is more a stable trait than a daily fluctuating feature, supporting the threat simulation theory's idea that individual differences in simulating threats interact with daily experiences.
