Lion
Psychological (Freud)
In depth psychology the lion embodies the powerful, commanding side of the self and courage, yet also the raw, dominating rage the ego fears. Confronting it may mirror a reckoning with a superior father or authority figure.
Oriental reading
In oriental-Islamic dream interpretation the lion usually stands for a powerful ruler, a stern sultan, or a fearsome enemy. One who overcomes or tames it is said to prevail over a mighty person or win their favor.
Animals
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
