The association between sleep disturbance and nightmares: Temporal dynamics of nightmare occurrence and sleep architecture in the home.

We collected measures of sleep architecture and nightmares from participants (N = 61) wearing the DREEM 3 headband across 2 weeks of data collection to test the hypothesis that there are bidirectional links between insomnia (measured as sleep disturbance) and nightmare events. Nightmares were predicted by increased sleep disturbance the night before the nightmare, but not on the same night or 2 nights before. We also found that nightmare occurrences did not predict increased sleep disturbance on the same night or the following 2 nights, rather nightmares predicted increased sleep disturbance at the between-subjects level only.

Benefits and concerns of seeking and experiencing lucid dreams: benefits are tied to successful induction and dream control.

Therapies focused on lucid dreaming could be useful for treating various sleep disorders and other conditions. Still, one major roadblock is the paucity of systematic information on the consequences of attempting these sorts of dreams. The current study sought to quantify positive and negative aspects of seeking lucid dreams, describe their phenomenology in detail, and identify features associated with positive or negative experiences.

The memory sources of dreams: serial awakenings across sleep stages and time of night.

Memories of waking-life events are incorporated into dreams, but their incorporation is not uniform across a night of sleep. This study aimed to elucidate ways in which such memory sources vary by sleep stage and time of night. Twenty healthy participants (11 F; 24.
