I recently started to realize that my face and body are just my physical shell, and that the real me exists only in my brain (not a big discovery so far, right?). I've become so aware of this that now, sometimes when I look in the mirror, I dissociate; it's as if I'm two people, my brain and my face. I can't really put it into words any better. But anyway, I was reading tweets on this subject, and someone said, "You are not your mind either," and it's true. In what they said, I understood, "You are not your thoughts either." I observe my thoughts from the outside, but yes, they are not me. Well! I'm very confused; perhaps I should revisit my definition of « mind ». So, my question is, if I am neither my physical shell nor my thoughts, who am I? The more I think about it, the more stupid and complex it seems at the same time. I would also appreciate some books recommendations on this topic, please?
