Whether you admire someone or you yourself are admired by someone else in your dream, both situations reflect the way in which you see yourself. If in your dream you admire certain qualities at an individual, this means that you are aware that you lack those and you would like very much to 'possess' them.
On the other hand, if you see yourself admired by others, the image may have two opposite meanings: it may relate to the fact that you have a rather low opinion about yourself and you need the admiration of those around you to boost your self-esteem. But it may also be the other way round, relating to the fact that you have too much confidence in yourself and you are rather a conceited and self-sufficient individual.
