From PsyPost:
People who have had COVID-19 tend to report having more nightmares than people who have not been infected by the virus, according to research published in Nature and Science of Sleep.
Previous research has indicated that the COVID-19 pandemic coincided with changes in sleep and dream activity among healthy individuals. A study published in 2021, for example, found that pandemic-related stress was associated having nightmares revolving around specific apocalyptic themes.
But Luigi De Gennaro, a professor at the University of Rome Sapienza, and his colleagues noted that whether dream activity in COVID-19 patients differed from dream activity in healthy people had not yet been investigated.

PG suspects a great many people experienced thoughts, fears, dreams, etc., etc., regarding “apocalyptic themes” during the past couple of years regardless of whether they were asleep or awake.
Also, erratic sleep, common to people struggling to breathe and to find a comfortable position, leads to more awakenings – and some of those are going to be in parts of sleep they don’t usually wake during.
Chronic illness has some of the same problems. It’s a sleep-deprivation problem.
