Prevailing mood, mood changes and dreams in bipolar disorder
1University of Alberta, Department of Psychiatry, Edmonton, Canada.
Abstract:
In this preliminary and exploratory study, we collected the dream reports and mood ratings of 6 outpatients with bipolar disorder over a 6-month period to compare the relationship between dream themes and mood states. We found that neutral mood states were associated with mundane, routine or uneventful dreams while manic states featured bizarre and improbable dream themes. Neither depressed nor mixed states showed a consistent trend in dream themes. By categorizing the dreams that preceded mood shifts, we were able to identify a particular type of dream that seemed to precede a mood shift, particularly in the direction of mania. Shifts to mania were heralded by dreams of death and bodily injury. Forthcoming depression was more clearly associated with a decrease in overall number of dreams reported. The significance of dreaming in relation to mood is discussed in terms of these preliminary findings and our bipolar dream scale is offered for the convenience of subsequent investigators.
Insights
Bipolar disorder patients
Area of Science:
- Psychiatry
- Sleep Medicine
- Psychology
Background:
- Bipolar disorder is a mood disorder characterized by shifts in mood, energy, and activity levels.
- Dream content and mood states are known to be interconnected, but specific relationships in bipolar disorder require further investigation.
Purpose of the Study:
- To explore the relationship between dream themes and mood states in outpatients with bipolar disorder.
- To identify potential dream markers that may precede mood shifts in bipolar disorder.
Main Methods:
- Collected dream reports and mood ratings from 6 outpatients with bipolar disorder over 6 months.
- Analyzed dream themes in relation to neutral, manic, depressed, and mixed mood states.
- Investigated dreams preceding mood shifts to identify predictive patterns.
Main Results:
- Neutral moods correlated with mundane dreams; manic states featured bizarre dreams.
- Depressed and mixed states did not show consistent dream theme trends.
- Dreams of death/bodily injury preceded manic shifts; decreased dream frequency preceded depression.
Conclusions:
- Dream content and frequency may serve as indicators of mood state and shifts in bipolar disorder.
- Specific dream themes (e.g., death, injury) and changes in dream frequency show potential as early warning signs for mood episodes.
- Further research with a larger sample is warranted to validate these preliminary findings and the proposed bipolar dream scale.
