Dream recall frequency is associated with attention rather than with working memory abilities.

People who frequently recall their dreams are more easily distracted by hard-to-ignore auditory stimuli than those who rarely recall dreams. Using a new task that tests selective attention and working memory together, the study found that high dream recallers were slower and less accurate when a distractor was difficult to ignore, while low recallers were much less affected. The groups performed similarly on working memory load. This provides the first behavioral evidence that attentional differences exist between high and low dream recallers, supporting the idea that attentional processes play a role in dream recall.
