A shift in dreaming patterns from the first to second wave of the COVID-19 pandemic
A year and a half ago, as the full scope of the pandemic that was descending on us became apparent, there was a global increase in severe stress, worry, fear and uncertainty. Reports of heightened dream recall and dream vividness were also on the rise, with many experiencing nightmare-like depictions of their greatest pandemic fears realized. This was a time of great upheaval and dysphoria, or, as Harvard professor and dream researcher Dierdre Barrett put it, “an extraordinary time in the history of dreaming.” Global dreaming trends can give us crucial insight not only into our collective mental state, but into how times of crises are reflected in our dream lives.
In Wuhan, a study of 100 nurses working on the front lines found almost half were experiencing nightmares (Tu et al., 2020) and an online survey of 811 individuals reporting dream content found 55% had pandemic-related dream content (Pesonen et al., 2020). As the first wave of the pandemic subsided, dream reports began to decrease. Many reported a “return to baseline” in both dream recall and emotionality (Scarpelli et al., 2021). But we all know this isn’t where the story ends.
Enter the delta variant, causing more infections and spreading more rapidly than its predecessor, plunging many countries into a second wave. So what happened to our collective dream lives during the second wave? Researchers are now sharing their answers.
In the spring of 2020, Scarpelli and colleagues released a web survey to “collect socio-demographic information, psychological and sleep measures, and dream variables” from participants in Italy. Then the second wave hit Italy in October of 2020, giving Scarpelli and colleagues the unique ability to conduct a longitudinal within-subjects study of oneiric activity in different stages of the pandemic.
The researchers released a second survey to the participants of the previous survey, designed to investigate dream changes during the second wave compared to the first wave of the pandemic, and 611 participants responded. They asked about dream recall frequency, nightmare frequency, lucid dream frequency, emotional intensity and nightmare distress. Interestingly, all variables, both quantitative and subjective, were lower in the second wave, yet the emotional tone of the dream content was more negative. Essentially, people are remembering their dreams less, apparently dreaming less, yet the dreams they do have are more negatively toned.
The Scarpelli study was not the only one that who found this. Conte and colleagues (2021) showed that “reported dream emotional tone became significantly more negative both in total lockdown and partial lockdown (second wave) compared to previous periods.” In addition, they found that waking mood was much more negative and fearful during the second wave. Since pandemic dreaming has largely been supporting the ‘continuity hypothesis’ that our dreams reflect waking life concerns, this suggests an over dip in mood and increase in fear which may reflect the fact that by now, most of us believed we would have put COVID-19 behind us. Instead, it seems increasingly unpredictable and lasting, and many people are losing patience and hope.
Each wave in each country hits the residents differently, and everybody rides the waves in their own fashion. Yet, after the devastating effects of the first wave in Italy, it is not difficult to imagine how facing a second wave could elicit negatively toned dreams in Italian residents. A German study by Moradian and colleagues found that during the second wave, participants had more depressive symptoms and exhibited less safety behaviours (such as handwashing and mask wearing), which they believed was evidence of “pandemic fatigue.” Another study by Kimhi and colleagues found that facing a second wave, participants had reduced resilience. After the shock of the initial wave, it appears that people are facing the second wave with a more resigned and negatively toned attitude, and this is what second-wave dream content reflects – less intensity but increased negativity.
With the dissemination of effective vaccines, it appears the waves of new infection have subsided from tsunami scale to a much more manageable level, especially among vaccinated populations. But vaccine availability and uptake is variable, and the waves continue to roll out in an unpredictable fashion, making this challenging time a kind of ongoing global experiment. The initial shock of the pandemic elicited such a strong shift in our collective dream lives that it spurred the publication of dozens of studies looking into dreams. Hopefully as the degree of disruption subsides, our shared interest in dreams will remain.
