Differences between groups based on recall frequency. (A) Comparisons between groups with dream-recall frequency without changes (=DRF; red bars) vs. decreased DRF (−DRF; blue bars) vs. increased DRF (+DRF; green bars) on Post-Traumatic Growth Inventory (PTGI) scores (relating to others (PTGI-RO), new possibilities (PTGI-NP), personal strength (PTGI-PS), spiritual change (PTGI-SC), and appreciation of life (PTGI-AL)), Pittsburgh Sleep Quality Index Addendum (PSQI-A) score, sleepiness, sleep disorders, and Sleep Hygiene Index (SHI) score. (B) Comparisons between groups with nightmare frequency without changes (=NF; red bars) vs. decreased NF (−NF; blue bars) vs. increased NF (+NF; green bars) on (PTGI) scores (PTGI-RO, PTGI-NP, PTGI-PS, PTGI-SC, and PTGI-AL), PSQI-A score, sleepiness, sleep disorders, and SHI score. (C) Comparisons between groups with lucid-dream frequency without changes (=LDF; red bars) vs. decreased LDF (−LDF; blue bars) vs. increased LDF (+LDF; green bars) on (PTGI) scores (PTGI-RO, PTGI-NP, PTGI-PS, PTGI-SC, and PTGI-AL), PSQI-A score, sleepiness, sleep disorders, and SHI score. Error bars represent the standard errors. Significant results are asterisked (* p < 0.05).
