Method: A sample of 169 volunteers rated their dream characters with adjectives. Character attributes related to anxiety upon awakening were analysed through an exploratory factor analysis with orthogonal rotation. Results: With 37 character attributes a KMO sampling adequacy index of 0.83 was obtained and 33.87% of the variance was explained. Four factors were extracted: Psychological Threat, Auxiliary, Terrifying Threat and Spectator/Victim. Their corresponding alpha coefficients ranged between 0.85 and 0.73 and three of the factors presented significant (p ? 0.05)correlations with the anxiety of subjects upon awakening. Conclusions: Our results indicate that self-report questionnaires about subjects? dreams are a reliable and valid alternative for assessing dream content. Information obtained about the characters allows for the assessment of the dream and provides indicators which allow for a simple interpretation, which does not contain biases due to the assessor or the ability of the subject to create a report. %N 2 %K Content analysis, dreams, nightmares, questionnaires, sleep, state anxiety %P 61-72 %V 20 %D 2008 %I SES - Sociedad Espa?ola de Sue?o %L cogprints7069
