SUMMARY:

Given that dreams play an important role in both implicit and explicit emotional regulation, we sought to demonstrate whether increased dream recording could influence this process. To investigate this association, 41 individuals (19 women) aged 18 to 35 were recruited and agreed to participate in the study. Participants were then divided into two groups and completed the Emotion Regulation Experiment (CERT) forms twice a year. After the first exposure to CERT, participants in the experimental group (G1, n = 21) completed a dream diary for 14 days to encourage an increase in the frequency of dream recording. The other group, the control group (G2, n = 20), completed a sleep diary. After this stage, participants underwent CERT again. During the two CERT periods, the Self-Assessment Manikin (SAM) instrument was used to assess emotional regulation based on exposure to negative and neutral images from the IAPS (International Affective Pictures System, 1979), and the oxygenation of areas of the cerebral cortex was monitored using functional near-infrared spectroscopy (fNIRS). Participants also completed questionnaires on sociodemographic, clinical, and dream conditions. Statistical analysis used the Mann-Whitney and Wilcoxon tests, with p-values < 0.05. The analysis of the results showed that the use of the Dream Diary was not effective in increasing the frequency of dream recording in group G1, when compared to group G2, although there was a trend toward significance (p = 0.081). It was also observed that G1 presented statistically significant lower activity in the anterior region of the Prefrontal Cortex post-intervention, evidenced by fNIRs. This difference was restricted to the Negative_Visualize condition of the CERT, according to SAM analysis, when compared to G2. This evidence suggests that describing one's dreams led to improvements in implicit, but not explicit, emotional regulation skills, since the difference between groups was not significant for the Negative_Reevaluate condition. SAM indices also indicated that, for participants in both groups, negatively valenced images did not achieve scores similar to those reported in the literature, which may have contributed to the lack of significant behavioral differences between the groups. Given the observed results, we recommend that future research on this topic be evaluated first, as possibilities for using more actionable stimuli to create emotional impact and that they also provide positively valenced images to balance emotional contexts.
