What does it mean to dream about son?
A son in a dream often stands for a quality you link with him or with sonhood, such as hope, responsibility, or your own younger self, rather than the literal child.
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 a son through the dreamer's wishes and worries about continuing the self into the next generation, and through older family feelings the figure stirs. He would ask what hope or anxiety about the future the son quietly carries.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the son as the child archetype, an image of new potential or of a younger part of yourself still growing. For a parent the figure can mirror what you are trying to pass on or protect.
Jungian concept (our summary).Modern
Continuity ties a son to your real concerns about him, or to the qualities of promise and duty you attach to him. Notice whether you feel proud, protective, or burdened, since that often echoes a waking situation.
Continuity hypothesis (our summary).Mythological
The son in myth ranges from the heir who carries a line forward to the young hero who must surpass his father. The figure tends to embody promise, inheritance, and the testing of a new generation.
