“Psychologically, the three-headed bird could represent a situation where the intellect feels ungrounded, dissociated, and thrown into an immobilizing state of confusion. Things that used to make sense just don't.”

The Wanderer and Settler express a conflict of will in the face of change.The house of the Wanderer wants to keep moving ahead while the dog is literally "driven" by compulsion. In the Settler on the other hand, the house remains stable in the midst of the moving ocean with the help of the whale's stability and the dog fixing his gaze on the stars. Balancing the opposite forces of pushing ahead vs staying still at this stage one can stay in the process and allow the unconscious to move things along.
