Parallel dreams dreams who’s meeting coincides with or supports the conscious attitude but in my experience, at least these are a rather rare.
Jung differentiates between a ‘subjective’ level and an ‘objective’ level to dreams. In the first perspective, the figures and elements of the dream are interpreted as representing parts or qualities of the dreamer’s personality (especially conflictual parts, i.e. complexes), whereas in the objective perspective, they are seen as representing persons or entities existing in reality. In dreams, the unconscious psyche attempts to support ego consciousness and foster a process of personality integration by pointing to parts of the psyche not yet integrated into the whole of personality, or to indicate unresolved conflicts. Through dreams, the unconscious, because it contains a more holistic knowledge about the development and integration of personality, brings new information to consciousness, which can then be integrated, if a conscious understanding of the information is possible. This is the aim of dream interpretation in psychotherapy.
