Abstract (summary)
Investigated the systematic resurgence in the incorporation of a daytime event into dreams following a period of several days, i.e., the 'dream-lag' effect. 10 male and 10 female Ss (aged 20–52 yrs) were shown a 30-min videotape depicting a ceremonial water buffalo slaughter by Naji villagers in Indonesia. Ss were instructed to write down their dreams for the next 7 nights. Two judges independently rated each report on a scale of 0–20, for the likelihood that some aspect of the videotape had been incorporated. Results provide evidence for the dream-lag effect. An initial tendency to incorporate, was followed by a decrease, and then a resurgence toward the end of the 1-wk period. This pattern was found only for those Ss who showed strong evidence of incorporation. However, the results may have been confounded by the Ss' awareness that the content of the tape was expected to be incorporated in dreams.
