Lucid dreaming—being aware of dreaming while still in the dream—relies on brain systems separate from those for ordinary dream recall. Using a multimodal neuroimaging approach, the study found that the frequency of lucid dreaming was predicted by a joint gray-matter and white-matter component involving frontal, temporal, parietal, and cerebellar regions tied to metacognition, imagery, and volitional control, plus a gray-matter-specific component in visual and attentional areas like the cuneus. Ordinary dream recall was linked only to two white-matter-specific components with no overlap. The results indicate that the tendency for lucid dreams depends on distributed, structurally covarying brain systems distinct from those for general dream recall.

Sleep paralysis (SP) is common in Pakistan, with 38.5% of participants reporting at least one lifetime episode. SP was significantly associated with higher PTSD symptoms, greater perceived stress, and certain lifestyle factors such as irregular sleep schedules and shift work. The findings suggest that psychological distress and disrupted sleep patterns may increase vulnerability to SP in this population.
