Dreaming in patients with cancer and their partners-an underestimated factor for quality of life?

Sleep disorders are prevalent among patients with cancer and their caregivers as well, affecting their quality of life. But the relationship between sleep quality, dream experiences, and life satisfaction in patients with cancer and their partners is understudied. The present research aimed to quantitatively investigate the dream experiences of oncology patients and explore the interdependence between patients and their partners in terms of dream experiences and life satisfaction. Therefore, a cross-sectional study was conducted with 101 dyads, completing a questionnaire assessing demographic and illness-related data, dream experiences, sleep quality, and life satisfaction. Inferential statistical tests and actor-partner interdependence models were used to analyse the data. Both patients with cancer and their partners reported on average a significant decrease in sleep quality since the cancer diagnosis and for both dyad members significant dreaming predictors for life satisfaction were found. Namely, a positive association for dream stability in patients, and a positive association for positive dream affect as well as a negative association for negative dream affect in partners. Regarding the question of interdependence, dream intensity exhibited a significant group-specific partner effect, but no overall partner effect, leading to inconclusive results that call for more studies in this field. The study suggests that dreaming may affect life satisfaction beyond sleep quality and underscores the significance of acknowledging dream experiences as potential influencers of quality of life in patients with cancer. Additionally, the study stands out for its examination of the role of partners in dyadic dependency, emphasising the importance of understanding their influence on patients' experiences.
