Association between dream mood and change in emotional valence. (a) A negative correlation between dream mood and overnight valence change for neutral pictures indicates more positive dreams are associated with more reduction in valence rating (rho = − 0.31, p = 0.03). (b) No significant correlation between dream mood and change in emotional valence was found for negative pictures (rho = − 0.08, p = 0.60).
