Wolf
Psychological (Freud)
In depth psychology the wolf often embodies the untamed instinctual forces and archaic aggression the dreamer fears or represses within. It can equally mirror a figure from the outer world experienced as threatening, onto which split-off inner impulses are projected.
Oriental reading
In dream interpretation after Ibn Sirin the wolf often stands for a treacherous, greedy enemy, a thief or an unjust man of power. One who overcomes a wolf is said to defeat an adversary, while being beset by it warns the dreamer to beware of cunning and betrayal.
Animals
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
