What does it mean to dream about skeleton?
A skeleton usually brings mortality or what is left bare to the foreground, the underlying structure of a thing or a reminder of the end.
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 skeleton as a stark reminder of death and of the body stripped to its frame. It can also hold the fascination and dread that the thought of dying stirs.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung would see the bare structure beneath the persona, what remains when all surface is gone. A skeleton can mark a confrontation with mortality the self must learn to hold.
Jungian concept (our summary).Modern
Continuity ties skeletons to waking thoughts of death, of old matters buried, or of the essentials left after everything else falls away. They often surface in seasons of loss or change.
Continuity hypothesis (our summary).Mythological
The skeleton is the dancer in the medieval dance of death, the leveller who takes king and beggar alike. Across traditions dry bones are the ground from which life is promised to rise again.
