Two founding texts of modern dream psychology both put a house at the centre. Freud, in The Interpretation of Dreams, listed the house among the standard dream symbols of the body, and his school read fronts, openings, upper and lower floors with cheerful anatomical confidence. The reading that has proved more durable came from Jung, who recounted a dream of his own: a house of several storeys, each lower floor older than the one above, descending from a furnished salon to a medieval ground floor, a Roman cellar, and beneath it a cave with primitive remains. Jung took the house as an image of the psyche in historical layers, and credited the dream with pointing him toward the idea of the collective unconscious.
That dream, told in Memories, Dreams, Reflections, is the ancestor of the now familiar reading in which the dream house is the dreamer, its rooms the compartments of a life, its cellar what lies beneath attention, its undiscovered rooms unrecognised capacity. The reading is Jungian property, not a neutral fact about houses.
The older handbooks were more literal, reading the fortunes of the dream house toward the fortunes of the household, damage and repair, inheritance and loss. Both registers persist, and a house dream may be approached through either without the other being wrong.
