Sorry Theorist, I don't really follow you at all. In the few short LDs I've had, my feeling of self was indistinguishable from my waking self. To me it seems you are over-complicating the idea of self when talking about the difference between lucid and waking self. To me it feels like waking, dreaming and lucid selves are all the same, but just under different influences by the level of consciousness. Even in non-lucid dreams, I still feel the same ''me", even if it's more fuzzy.
I do accept that there might be an alter ego in the form of the unconscious, as has been described by Waggoner (IIRC), but I have yet to experience this.
