Abstract

Summary: Dreaming and insomnia are important markers of distress in times of crisis. Here, we present a longitudinal, mixed‐methods study examining changes in dreaming between individuals with and without insomnia symptoms and their relationship to mental health during the COVID‐19 pandemic. A global survey examining insomnia symptoms, dreams and mental health was launched in April 2020 and followed participants over 12 months. Of 2240 participants, 1009 (45%) reported dream changes at baseline. A higher proportion of participants with new‐onset insomnia reported dream changes (55%) than those with pre‐existing insomnia (45%) or good sleepers (36%). Overall, thematic analysis identified key dream change themes of increased dream activity, with participants dreaming vividly, in high‐definition, and with a strong negative charge. Themes around survival, adjusting to pandemic life, meaning‐making and poor sleep quality were also noted. Linguistic Inquiry Word Count showed that individuals with insomnia used more negative words to describe their dream changes than good sleepers. Specifically, the new‐onset insomnia group used more anxious and death‐related words than those who slept well. Notably, all groups experienced a significant reduction in dream activity by 3‐month follow‐up. Lastly, dream changes were associated with worse mental health symptoms over time, and this effect was more pronounced in individuals with insomnia. Our results highlight that insomnia symptoms, especially new‐onset insomnia, are associated with more negative dream changes during collective stressful events, potentially compounding daytime distress and mental health symptoms over time. During times of crisis, dreaming and insomnia may reveal an important target for mental health interventions.
