Pupil Size Indicates Which Memories We Relive In Dreams: Study

A recent study published in the journal "Nature" has explored the connection between pupil size and the vividness of memories that reappear in dreams. Researchers found that the dilation of pupils can serve as an indicator of how intensely a person is reliving a memory during sleep. The study involved participants recalling memories while awake, with their pupil sizes monitored, and then comparing these to the memories they reported from their dreams. The findings suggest that memories associated with larger pupil dilation when awake are more likely to be vividly re-experienced in dreams. This research not only provides insights into the mechanisms of memory processing during sleep but also opens up potential new avenues for understanding dream content and its relation to emotional and cognitive states.
