The mirror is not so rare a dream element as has been thought; and its appearance may mark a critical point in an analysis. Intact mirrors with clear images are reported when the dreamer has made a creative integration of previously threatening material, while mirrors that are shattered or multiplied or without reflection are accompanied by evidence of terror and a lower level of psychological organization. Study of mirror dreams can further clarify the nature of the dream screen and the role of illusion in early interactions and development.
