Dreaming or Dreamtime is a complex and important concept in Aboringinal beliefs and tradition. It refers to the mystical time of creation. Legends from the Dreamtime tell of this creation. They give reasons for the existence of things, like the birth of the first human beings. the existence of different kinds of animals, the formation of the distinctive geographic features, the various phenomena of the sky and the changing climates...According to the Gagadju, life and the natural features of the land only began to take shape during the Dreamtime. They were all created by spirit ancestors. After completing their creative tasks, the spirit ancestors didn't just disappear. They turned themselves into different things...rocks, pools, paintings, rock arts etc. They still retain the power and creative energy within them.
Each Gagadju has several totems which are of his Dreaming. They can be Dreaming animals or plants. They believe they are descended from the same spirit and possess some of their life essence of the Dreaming species in them. For example, if a man belongs to the Wallaby Dreaming, by painting Wallaby design of his body during cerenomy, he becomes a wallaby. In his life time, he has a special relationship with the wallaby and become very close to it. The wallaby can guide him to good hunting grounds and warn him of any danger. And he will not eat them.*
Each Aboriginal group has its own legends which are related to the land they occupy. Therefore, Aborigines in different parts of Australia will tell you different origins and how their mountains and rivers came to be. Members of an Aboriginal group believe they all came from a common ascentral being who left behinds rules and regulations to govern the correct behaviour.
