Much less research supports the dream-lag effect, however.
Dreams were then judged for the extent to which they incorporated these daily events. At present, imprecision in report collection and other conservative features of the experimental design, as well as findings from previous studies, do not warrant complete rejection of the notion of dream-lag effect. Half the subjects were of each sex. Sixty-one subjects returned one year later for repeat sleep and dream recording. This tendency becomes exacerbated during a depressive episode.
