In Korean tradition, dreaming of a cave is read as mixed. It is most often tied to 전반, 건강.
The cave is the womb and what lies hidden. Entering was read as seeking something concealed or a time to withdraw; emerging, a fresh start.
Tradition reads the symbol as an omen; psychology reads the same dream as a mirror of your present state. Describe your dream and both readings appear together. Interpret your dream
