(1) A fight may represent conflict in a real-life domestic or work situation.

(2) The conflict may be within you, between opposing forces in the psyche. An obvious candidate is a clash between what you want to do and what you feel you ought to do. In this case, bear in mind that conscience is usually socially constructed and consists of the prohibitions and ideals that were imprinted in your psyche during your early years.

(3) The conflict may be between what we are in fact and what we are potentially. Jung sees conscience as the voice of inner wisdom that will lead us to our true selfhood.

(4) If the conflict is between conscious ego and unconscious, the aggressor in the dream fight will probably represent the part of you that is demanding release from the dungeons of the unconscious. It will not hurt you unless you deny it expression. Identify it, and then welcome it as a talent or energy that can contribute to your well being. Change the conflict into a dialogue, a respectful exchange between your conscious and unconscious. (Is this not the way to handle such situations in our waking lives, instead of aggression?).

Where there is unresolved inner conflict, there is a tendency to project the unconscious protagonist to other people, often with dire consequences in personal relationships.

(5) More specific inner conflicts are those between opposite psychic qualities or forces, such as masculinity and femininity, thinking and feeling.

Devil

Basic Meaning - A fear of those repressed contents of the unconscious that are, when acknowledged the very forces that could bestow a harmonious and balanced life.

(1) The Satan of Jewish - Christian - Islamic tradition was originally a horned fertility god, a personification of the fertilizing power of Nature {the tradition of God is separate from Nature}. In psychological terms, a fertilizing agent is something within the psyche that can inaugurate a new phase in the individual's development.

(2) The evil connotations of the devil figure may reflect the dreamer's fear of those repressed contents of the unconscious that are, in fact, the very forces that - if mobilized and utilized - could bestow a new and fuller life. What we repress is invariably something that had great value for us but on some occasion in the past gave rise to guilt-feelings or a fear of punishment. It is our fears that invest the unconscious with the fearsome characteristics of a dark underworld inhabited by evil monsters. In reality, the unconscious contains all the energy and wisdom we need for healing and wholeness.

It might be said that our fundamental human task is the conversion of the devil within ourselves, that is, converting negatively charged {dissident, destructive} psychic forces into positively charged {life-enhancing and unifying} powers. But you won't convert the devil with brute force, only with love. The negatively charged psychic forces are the ones you neglect and despise or fear. They become positively charged when you acknowledge them and integrate them into your conscious life.

If we do not recognize the "devil" within ourselves, we shall project him onto others and thereby give more scope for hatred and destruction {the real devil!} in the world.

{3} In certain contexts - if, for example, he has horns or is sexually involved with naked women - the devil may be a sexual symbol. If sexuality is repressed in such a guise in a woman's dream, it is possibly because she has a fear of sexual relations. In a man's dreamthe indication might be that he has a guilt-ridden attitude towards his own sexuality {which Freud might trace back to anxiety arising out of the normal male infant's erotic feelings for his mother}.

Demons

Demons in dreams probably represent parts of your unconscious mind that have been repressed and neglected and are now threatening to disrupt or mutilate the psyche. They should be approached lovingly, given attention and integrated into your conscious life. This will bring about their "conversion": They will cease to threaten and will contribute their vital energies to the enhancement of the self.

Self-knowledge - knowing what we are carrying around with us in our unconscious - is the only sure defence against what in ancient times was called demonic possession, which in psychological terms means the conscious ego being taken over by unconscious forces {obsessive fear or anger, or whatever}.

Dragon:

Animal instincts to be conquered, hence the battles of Saint George and Saint Michael with 'the dragon." The dragon fight is related to the archetypal themes of search/quest, the hero/heroine, and, in more modern terms, separating ourselves from the collective values of our parents/ancestors. The dragon can symbolize a guardian or guarding quality; something that needs to be guarded/protected in your life/psyche. As a devouring creature, it may represent negative aspects of the mother archetype. It shares much of the same symbolism as the snake, and both can symbolize the developing Self
