Thinking that we are all nothing but shadows in this life, because we disappear once the light put upon us is out, makes me consider more the final part of the shadow's definition - reverse projection of the object blocking the light. This makes a huge difference between what we are and what we seem to be, about what or body movements show and what our mind is actually thinking. Nowadays I think it's difficult to make the difference between these things because people hide their real feelings and try to show the reverse image of what they think just to obtain something. The shadow definition is more that applicable in some cases. I'm not talking only about love and emotional feelings. We project our shadow in the society because we are either afraid of what we actually are or because we just want to protect and seal our true feelings.
