They slept well, but negative emotions weighed more heavily in their dreams
Among 50 healthy adults, those who said they slept well rated negative emotions in their dreams as more intense. Among those who slept worse, the two were more evenly matched.
The key idea
In remembered dreams, those who said they slept well rated negative emotions as more intense. Among those who slept worse, the two were more evenly matched.
The study, in plain language
When you wake up, you can remember an unsettling dream and still feel that you slept well. The team explored this relationship by asking healthy adults to describe a remembered dream, their emotions from the previous day, and their usual sleep quality.
Among those who said they slept well, negative emotions in the dream received higher ratings than positive emotions. Among those who said they slept worse, the two were more evenly matched. This second group also reported more lucid dreams, in which you know you are dreaming, while the difference in nightmares was not strong enough to support a firm conclusion. Questions about dreams captured experiences that did not follow a single pattern.
What they found
- Each participant described a remembered dream, and the team compared responses with a sleep questionnaire.
- Those who said they slept well rated negative emotions in their dream as more intense than positive emotions.
- Among those who slept worse, positive and negative emotions in dreams received more similar ratings.
Something to think about
When you wake up, note separately how you think you slept and what emotion you remember from the dream. They may not always go together, as in this study.
How they studied it
In Italy, 50 healthy adults aged 19 to 52 took part in a dream-recording phase. A questionnaire grouped them by their self-perceived sleep quality, and each person reported the emotions in a remembered dream and those from the previous day. The groups were compared without an intervention.
What the study cannot show
- Few people completed the dream log.
- Waking recall and personal responses may influence what people report.
- Sleep quality was neither manipulated nor measured with polysomnography.
