What Does Dreaming of a Dog Mean?
Traditional Interpretation
According to Ibn Sirin and Islamic interpretation, the dog is generally read along the axis of loyalty and enmity: a tame, faithful dog can point to a trustworthy friend or guardian, while an aggressive or barking dog may signify an immoral enemy, gossip, and slander. Imam Nabulsi treated the dog as a "weak enemy"; driving a dog away may indicate getting rid of an enemy, while being bitten by one can point to being harmed by someone you trust.
Psychological View
In modern psychology, the dog can, in Freudian terms, represent instinctual drives along with dynamics of loyalty and obedience, attachment, and one's sense of trust. Jung, in particular, interprets the black dog as the "shadow archetype"; this may point to repressed aspects of oneself that are hard to accept.
