What does it mean to dream about trunk?
A trunk often points to stored memories or a past you keep packed away, so notice whether you opened it eagerly or feared what was inside.
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 the locked chest as a container for hidden contents, the wishes and memories shut away from view. Opening it can stir both longing and dread for what has been stored out of sight.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the trunk as a vessel of the past self, the keepsakes and buried parts of your story. What you find inside can be an inheritance from who you used to be.
Jungian concept (our summary).Modern
Continuity ties a trunk to waking thoughts about the past, keepsakes, and things you have packed away rather than dealt with. Opening an old trunk often echoes a real return to memory.
Continuity hypothesis (our summary).Mythological
The chest that holds what must not be loosed runs through myth as the sealed box whose opening let loose troubles upon the world, leaving only hope behind. To lift the lid was to risk what was better kept shut.
