Meaning
To be in a state of natural rest during which the eyes are closed.
Cultural Background
The concept of 'Pali-pali' culture often makes sleep a secondary priority to work and study. However, 'Well-sleeping' is a growing trend. Traditionally, Koreans slept on the floor using a 'Yo' (quilt) and 'Begae' (pillow) with buckwheat husk filling. Young Koreans use the term '꿀잠' (honey sleep) frequently on social media to describe a satisfying rest. The distinction between '자다' and '주무시다' is a cornerstone of Korean social hierarchy and respect.
