Several studies have found a high incorporation of waking life events intodreams that occur during the following night (day-residue effect), then a decrease inincorporation into dreams over the next 2 to 4 nights, followed by a resurgence ofincorporation into dreams 5 to 7 days after events (dream-lag effect). These studiesinvolve dream diary and daily diary keeping across a 1 to 2 week period, after whichparticipants or judges give a single rating to the degree of correspondence betweeneach dream report and each diary record. In the current study, participants (3 males,11 females; mean age 50.62 years) rated separately the intensity of as manycorrespondences as they could identify between each dream report and each diaryrecord. From these multiple ratings, summary variables, including total number andtotal intensity of correspondences, were computed for periods between the daily diaryand occurrence of the dream of 1 to 10 days. The dream-lag effect was not found. Theday-residue effect was found for a group (n 7) defined as having identified a belowmedian total number of correspondences across the study. It appears that individualswho identify large numbers of correspondences dilute the day-residue effect.Suggestions are made for personality characteristics of such individuals, who displaywhat may be akin to a Barnum effect in their response to the comparison of dreamreports to daily diary records.
