What does it mean to dream about bread?
Bread usually points to basic provision and what sustains you, the daily sufficiency of having enough.
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 bread as a figure of appetite and nourishment, the early link between being fed and being loved. Sharing or withholding it can stand for giving and receiving in a relationship. The hunger in the image may matter more than the loaf itself.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung would see bread as a symbol of common sustenance and of what is shared at the table of the self. It can mark the simple ground on which a life rests. Your own feeling about plenty or want is the place to begin.
Jungian concept (our summary).Modern
Continuity ties bread to waking thoughts about money, security, and providing, the question of whether there is enough. It may surface after worry about the household or after a satisfying meal. Notice whether the bread was fresh, stale, or shared.
Continuity hypothesis (our summary).Mythological
Bread is the staff of life across cultures, broken to seal fellowship and offered to the gods as firstfruits. The grain that dies and rises again made bread a sign of renewal long before any one faith claimed it.
