Hero
If you are the hero in your dream, your subconscious is showing the idealistic view you have of yourself in terms of relationships with others.
Are you "trying" to save someone or everyone from a bomb or disaster? This is the burden you place upon yourself to please or save people.
Are you being saved by someone or waiting to be saved by someone? This is your inner desire to be saved by someone or some external force. Who you are being saved by indicates the characteristics that can save you. It is more than possible that this person is actually you in disguise. There is a calling for you to step up to the plate and be your own hero. The person who is saving you in the dream is inside of you. Learn how to bring out their characteristics that you admire.
Does the hero fail? This indicates the need to implement a different strategy when dealing with problems in real life.
