Italian scientists from the Sapienza University of Rome report that during the pandemic, the quality of sleep has worsened on average among the population.
The two-week study involved 90 volunteers. The first week (April 28-May 4, 2020) took place under the conditions of a hard lockdown, and the second (May 5–11) during the period of partial lifting of restrictions. The subjects were asked to write down their dreams at home and complete a sleep diary every morning.
According to the data obtained, people began to fall asleep worse, wake up more often at night, remember dreams better and have more lucid dreams than before the lockdown. In addition, participants also reported having frequent dreams about being in crowded places.
The researchers conclude that the pandemic has become a “collective trauma” for the population — in line with observed dreams and worsening sleep quality. And the increase in the proportion of lucid dreams during the lockdown may reflect the human psyche’s attempt to cope with the waking experience of the pandemic.
