Snakes fascinate and terrify most of us. Because of this near universal reaction, and because snakes have played such important roles in the mythology of just about every religion, we know they have relevance to the psycho-spiritual life of every human being.
In our ignorance it is easy to misinterpret the meaning of trees. For example, in an early dream I passed by a tree so loosely rooted that the trunk shifted when I touched it and I was afraid it would fall over. Another dream around the same time featured a flimsy willow tree whose roots were so soggy from the nearby swamp that it, too, was in danger of falling and dying.
