1- In less sophisticated times bread, because it was made from grain, was also a fit offering for the gods. It was formed into loaves which then became symbols of fertility, nourishment and life. This symbolism remains visible today at Harvest and Jewish festivals. In dreams, loaves can represent our need for nourishment.
2- The Biblical parable of five loaves and two fishes signifies the principle of being fed through caring. In most cultures, the sharing of a loaf denotes friendship. It can have the same significance in dreams.
3- Spiritually the loaf represents the Bread of Life, the love of God and charity in the sense of caring.
