Abstract: The Dark Triad (i.e., Machiavellianism, narcissism, and psychopathy) of personality has been associated with behaviors that facilitate a fast life history strategy, such as aggressiveness and increased interest in sex. In the present on-line study (N = 265), we investigated the possibility that these personality traits have an association with dream content, namely, increased frequency of sexual and aggressive dreams. In regression analyses, we found that the frequency of aggressive dreams was predicted by Machiavellianism and psychopathy. The frequency of sexual dreams was predicted by psychopathy and narcissism. The results support a number of previous studies, suggesting that especially psychopathy is a manifestation of a fast life history strategy. Further, individuals high in this trait may simulate evolutionarily relevant actions in their dreams.
