What does it mean to dream about banana?
A banana usually carries simple nourishment and, by its shape, sometimes a more playful or sexual reading.
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 was famously alert to the shape of such fruit and would read a possible phallic suggestion, a figure of male sexuality. He also warned that a fruit is sometimes only a fruit. The feeling around it tells you which reading fits.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung would set the literal reading aside unless the dream presses it, and look instead at the banana as ordinary sustenance. It can stand for ease, plenty, or the tropical and carefree. Your own associations are the surer guide.
Jungian concept (our summary).Modern
Continuity ties the banana to waking thoughts of food, health, and the small details of the day. It may simply carry over a meal or a craving. A slip on the peel can also bring in a fear of public mishap.
Continuity hypothesis (our summary).Mythological
The banana belongs to the abundance of tropical lands and figures in their stories of plenty and of origin. In some island myths it stands against the stone as the choice of mortal, fruitful life over barren permanence.
