Paranoia in dreams and the classification of typical dreams

Abstract

The present study was geared toward expanding the previous evidence for the thematic similarities between dreaming and psychosis. Themes derived from delusions that characterize psychotic and schizophrenia-spectrum disorders, together with the modified Typical Dream Questionnaire, were administered to 280 Chinese participants from Hong Kong. These delusional themes served as some continuous variables for evaluating the degree to which the narrative contents of dreaming can be compared with those of psychotic and schizophrenia-spectrum disorders. It was found that delusions of various types, with various levels of bizarreness, could be observed in dreams. This was particularly true for themes involving paranoid suspiciousness, such as blaming others for making troubles and feeling that others are not giving proper credit for one’s achievements, which were dreamed by a majority of the participants. The current findings generated by the exploratory factor analyses precisely replicated Yu’s (2009) previous delusional model that classified dream themes into the Ego Ideal, Grandiosity, and Persecution categories. Moreover, the present study expanded the Ego Ideal category, developed measures for assessing the delusional inclination during dreaming, and discussed the reciprocal, triadic dynamics between the three major categories of dream themes.
