The continuity hypothesis of dreams suggests that the content of dreams is continuous with the dreamer's waking experiences. Given the unprecedented nature of the experiences during COVID-19, we studied the continuity hypothesis in the context of the pandemic.

Although new learning is known to reappear in later dream scenarios, the timing of such reappearances remains unclear. Sometimes, references to new learning occur relatively quickly, 1 day post-learning (day-residue effect); at other times there may be a substantive delay, 5-7 days, before such references appear (dream-lag effect). We studied temporal delays in dream reactivation following the...

Yet little research has focused on the relationship between nightmares and the subjective experience of sleep quality. In this study, we aimed at investigating the relationship between nightmare frequency, subjective sleep duration, subjective estimation of...

Case Report. In order to further characterize clonidine's role in treating nightmare symptoms in PTSD, we...
