Hillman is describing a specific texture of loss that the soul knows well — not grief, which moves toward resolution, but something more like a structural incompleteness baked into the experience itself. The underworld is not a place of death tidied up; it is a place of the insufficiently dead, the shades who want blood precisely because blood restores the thickness of three-dimensional presence. They hunger for what they gave up in order to become images.

What the dream carries, then, is not a message to decode but an incompleteness to tolerate. The "lost bit" Hillman names is not a failure of the dream's communication — it is the dream's actual content, the negative space that defines the shape. Every attempt to complete it, to pull the remainder into waking comprehension, is already a movement back toward the surface, back toward thymos and appetite and the body's insistence on fullness. The soul in the underworld register does not want completion; it is asking you to hold the concavity without filling it.

This is where the hunger for interpretation betrays itself. Reaching for what the dream "really means" is the same move as wanting blood — restoring volume to what has thinned itself deliberately into image. The incompleteness is not a defect. It is how depth keeps its depth.
