The Rebel, this topic of self, no self or sense of self is of interest to me. I don't have any answers for you. I do think our sense of self, that is sense of a separate "I"/"me" starts when we learn our name and perceive ourseves to be a separate being. Here is an article about Neuroscience and Buddusim that may help you:
It sounds like you are doing some meditation. This question of just who are we refering to when we say/think "I am" is central to the path of spiritual awakening in Buddhism. I find a teacher named Adyashanti to be quite understandable from a Western perspective. Don't let his references to Christian mystics throw you-- he has a lot to offer.
