From: Evidence of an active role of dreaming in emotional memory processing shows that we dream to forget
Association between total sleep time (TST) and overnight change in d’ for negative images for (a) non-dream-recallers and (b) dream-recallers. (a) A positive correlation between TST and overnight d’ change for negative pictures indicates longer sleep duration is associated with better overnight memory consolidation for negative images in non-dream-recallers (r = 0.37, p = 0.005). (b) No significant correlation between TST and overnight d’ change was found for dream-recallers (r = 0.15, p = 0.32),
