Carl Jung: The Hook of Projection
It frequently happens that the object offers a hook to the projection, and even lures it out.
This is generally the case when the object himself (or herself) is not conscious of the quality in question: in that way it works directly upon the unconscious of the projicient.
For all projections provoke counter-projections when the object is unconscious of the quality projected upon it by the subject.
