The basement is the house's underworld — beneath awareness, where the foundation shows and the unwanted is stored. Descending the dream-basement is descending into the personal unconscious: what the household of self keeps below.
Positive Resonance
The foundation inspected, the stored-below reclaimed, depth of the house known
Shadow Aspect
What is kept beneath awareness, the fear at the bottom of the stairs
Nuances
Descending in the dark: the unconscious entered
Something living down there: the disowned inhabiting below
