In a dream, the sea can symbolize the emotions, so an admiral in a dream can represent the part of you that directs the way you navigate through difficult emotions.
You may dream of an admiral when you are going through emotional turmoil in your waking life and are in need of an inner guide.
If you are the admiral in your dream, your unconscious could be telling you that you have the strength to get though a difficult time; you need to find that strength within yourself.
A dream that an admiral is shouting orders at you can mean that you feel that others are trying to force you down the wrong path.
