Who are you ?! Who am I ?!

We all think we know who we are, but is it true ?!
Maybe beyond who we are, beyond who we think we are, there is something more ...
We are each one of us, (I am me, and I am what I want to be, and so are you and everyone around us) but at the same time we are someone else, we are pieces of the soul taken from someone else ... And I'll explain why I say that.
Someone once said that every person in our life shapes our life and soul, and when they leave us or our life, some of them stay with us forever. Thus, no one really dies, never, They live through us ... that's why I say, the fact that we are not just us, as we believe ... but we are pieces of the soul taken / left by those who are or they were dear to us .... and how our life can include many dear people over time and years .... our soul and personality is like a universe full of stars, each star representing a piece of soul taken / left by someone .... we can have in our soul a good lesson from our grandmother, or from a dear friend, and that lesson, that piece of soul can belong entirely to that person or can be much older than that, and I say this because that person may have that life lesson from his own experience, or he may come from someone else who was once part of his life, and so .... 1, that person will always live, offered from the heart in soul ... 2, we are all connected, even with people we didn't know or not u we will never really know them maybe .... So ... who are we ?! .... although we know who we are .... but a part of us ... we will never really know .... (when I say a part of us, I do not mean people but the soul ... )
