Because our dreams are our own creation, it is very common for a dreamer to experience the role of "hero" within a dream. Usually this is a sign that the person is very confident in life in general, or in a specific aspect of their life which is addressed in the dream. The fact that you are the hero in a dream may arise soon after you have accomplished something. It is even better to have such a dream just before taking on a challenge of some sort in your waking life.
The fact that you may find yourself enhanced with incredible skills or superhuman powers is noteworthy.
What special skills did you have in the dream?
Were there any recognizable people in the dream? If so, their presence may indicate the area to which you should attribute the dream's implied meaning-business, home, or leisure pursuit.
