In Korean tradition, dreaming of a grandparent is read as auspicious. It is most often tied to 가족, 전반.
Grandparents and ancestors guard the house. Smiling or giving something was read as blessing or a conception dream; a worried face, look to the family.
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
