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 grapes as ripe pleasure, a cluster of small satisfactions ready to be taken. They can carry the wish for ease and indulgence. Sour or out of reach, they may mark a desire frustrated.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung would see grapes as a sign of fertility and of the harvest gathered, the raw matter of wine and of transformation. They can mark the reward of slow growth. Ask what in you has ripened to the point of being gathered.
Jungian concept (our summary).Modern
Continuity ties grapes to waking thoughts of plenty, reward, and the enjoyment of what you have worked for. They may follow a harvest of effort or a wish for one. Whether they were sweet or spoiled can colour the feeling.
Continuity hypothesis (our summary).Mythological
Grapes are the gift of Dionysus and the emblem of the harvest's plenty, heavy clusters carried home in triumph. The spies' great bunch from the promised land made the grape a sign of a good country and of abundance ahead.
