CL – It means that you had an experience of being a Shape-Shifter. It is something than many ancient people speak about, that they know the different animals they live with, and treat them with holy respect.
In the Once and Future King, Merlin in his training to be a magician or shaman, went through many animals forms. This is also something that happens in the initiation of someone who has found their way to the thing that has many names: the Mother Church; the Eternal Flame; the Great Spirit and so on.
So maybe this is not the only shape you will know.
