What does it mean to dream about wood?
Wood often stands for material once living now put to use, the raw stuff of building and warmth, or the memory of growth turned to substance.
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 ask what the wood was for, since timber can serve building, burning, or simple keeping. Cut wood may stand for energy gathered and stored, or for something living put to a hard purpose. What you meant to do with it can shade the meaning.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see wood as the durable substance left by growth, life turned into something that can shelter and warm. It carries the memory of the tree even as it becomes useful matter. Working with wood can speak of shaping the self's resources into a lasting form.
Jungian concept (our summary).Modern
Under continuity, wood tends to follow waking thoughts about building, repairs, fuel, or practical resources. A stack of timber may mirror plans or provisions you have laid in, while rotten wood can track something no longer sound. Consider what you have been making or maintaining.
Continuity hypothesis (our summary).Mythological
Wood was the body of the sacred grove and the matter of the world tree in many traditions, holy before it was useful. Certain timbers were thought to carry protection or fortune into the homes built from them. So wood carries both the memory of living growth and the strength of what endures.
