Between Living and Dreaming Vox Obscura

rückkehrunruhe

n. the feeling of returning from an immersive trip only to notice it fading rapidly from your awareness, as if your brain had automatically assumed it was all just a dream and already went to work scrubbing it from your memory.

German rückkehren, coming back + Unruhe, restlessness. Compare Zugunruhe, "migration restlessness," the fidgety behavior observed in birds approaching mirgation. Pronounced "rook-kair-oon-roo-uh."
