What does it mean to dream about king?
A king often stands for authority, power, or the ruling principle in your life, or for your own sense of mastery, rather than a literal monarch.
Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud would read the king as a father figure of supreme authority, the one who commands and judges. He would look for the dreamer's feelings toward power and the wish to rival or replace it.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung would see the king as an archetype of order and the governing self, the centre that rules the inner kingdom. An aging or ailing king can mark a ruling attitude that needs renewal.
Jungian concept (our summary).Modern
Continuity ties a king to waking concerns about authority, ambition, or who holds power in your life. The figure can reflect your own standing or your relation to those who command.
Continuity hypothesis (our summary).Mythological
The king runs through myth as the figure whose health is the health of the land, the sovereign who must rule well or fall. The figure tends to embody order, responsibility, and the burden of the crown.
