Dreaming of a cockerel is an indication of aggression, and desire to be alpha male of the group. You are all about marking and protecting your territory. Enemies fear confronting you head on, while there are many who plot behind your back to topple your position of power. Continue to monitor your possessions, and grow in the image of the cockerel.
You might be feeling a sense of assertiveness or confidence. Cockerels are known for their loud, assertive crowing, and a cockerel in a dream could symbolize feelings of assertiveness or confidence. If the cockerel is crowing loudly and confidently in the dream, it could suggest that you are feeling assertive and confident in your waking life, or that you are seeking these qualities. If the cockerel is quiet or subdued in the dream, it could suggest that you are feeling uncertain or insecure in your waking life.
