Testing affect regulation theories of dreaming.

Area of Science:

• Psychology
• Neuroscience
• Sleep Science

Background:

• Dreaming is theorized to regulate waking emotions, akin to exposure therapy's fear extinction.
• The relationship between dream content, waking affect, and emotion regulation strategies requires further investigation.

Purpose of the Study:

• To investigate if dream fear correlates with reduced negative affect (NA) and increased positive affect (PA) upon waking.
• To examine the moderating roles of emotion regulation strategies and mixed dream emotions.
• To determine if individuals with higher dream fear exhibit enhanced adaptive emotion regulation.

Main Methods:

• Utilized a natural language processing tool for dream content analysis.
• Employed Bayesian multilevel modeling on daily survey data from a community sample (N=536).

Main Results:

• Frightening dreams were associated with a 7% increase in morning NA (p=100%).
• Dreams with concurrent fear and joy increased the odds of zero morning NA by 20% (p=97.82%).
• Higher average dream joy correlated with 9% higher morning PA (p=98.79%).
• Individuals with higher average dream fear demonstrated greater adaptive emotion regulation (β=0.18, p=99.93%).

Conclusions:

• Dream emotions influence waking affect, supporting affect continuity but also individual regulation.
• While frightening dreams can worsen morning affect, especially in high-regulation individuals, mixed emotions and dream joy are linked to better morning affect.
• Findings suggest dream emotions play a dynamic role in psychological functioning and may be a target for mood disorder treatments.
