Mammoth
Our personality is a young new thing. It grows throughout our life, but its roots reach into the processes of life and consciousness active in our own being, which are as ancient as life on this planet. Life on the planet is also only an extension of processes active in the cosmos. So in dreams we often sense this primordial past out of which our present self has grown, and frequently depict this meeting as a prehistoric animal such a dinosaur or mammoth.
When you were conceived you were at the very beginning of life forms. In fact we have to go to the very primal to reproduce. That may not mean much to most people, but in the dream world it means an enormous amount. Because from there we go through the whole process of evolution as we are in our mother’s womb. Again, most people say, “So what. I don’t remember!” You remember not in ordinary memories, but in ancient feelings of fear, or religious wonder or even intuitions of life’s meaning. But of course we do and such memories are seen in our dreams. So when you learned language you forgot all the past.
