The patient should be encouraged to mention any feelings, memories, or seemingly unrelated thoughts that come to his mind during this process.
Focusing on the dreamer's associations (rather than upon the manifest content that evoked these associations) serves to clarify what these images mean to the dreamer, and hence why his mind selected these particular images.
In the case of psychosis, the subject 'turns away' because the conscious mind cannot handle reality, and so allows the unconscious to redefine the world.
It is an extreme means of repressing unpleasant thoughts that the real world forces on the subject.
When these urges are too deeply hidden, the dreamer's mind reacts with alarm and wakes him before the repressed content can harm him.
Having explained the practical task of dream interpretation, Freud discusses the theoretical task of explaining the dream work.
Next, Freud discusses the common resistance to dream analysis.
He admits that the technique is limited, especially because it must work against many resistances that a patient might have to analysis.
These resistances can hinder dream interpretation, but they are also significant because they arise from the same origin as the dream.
In other words, they are born from the same psychological issue that prompted the dream.
