What does it mean to dream about valley?
A valley often pictures a low point or a sheltered passage between heights, a place of rest, of hardship, or of moving through to the other side.
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 low, enclosing landscape as a place of shelter and sometimes of feminine or maternal symbolism, ground that holds and surrounds. Its mood may mark whether that holding feels safe or confining.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the valley as a low stage in the journey of the self, a passage between peaks where one rests or labours before climbing again. Such low ground often precedes a renewal.
Jungian concept (our summary).Modern
The continuity view ties a valley to waking feelings of being in a low season, sheltered or subdued, or of passing through a hard stretch. The sense of the place usually points to where you feel you stand.
Continuity hypothesis (our summary).Mythological
The valley of shadow is a long-standing image of the hard passage one must walk through, and sheltered vales were also imagined as hidden, blessed places. The same low ground held both fear and refuge.
