The Neural Architecture of Dream Recall Frequency: Insights from Interindividual Variations in Brain Structure and Function

People who frequently remember their dreams tend to have specific structural and functional differences in brain regions linked to memory and attention. The medial prefrontal cortex, temporoparietal junction, and hippocampus show greater gray matter volume in high dream recallers, while the same regions exhibit stronger spontaneous activity during rest and sleep. These findings suggest that dream recall is not a random phenomenon but is tied to stable, measurable variations in the neural systems that support memory encoding and retrieval.
