... More specifically, my “Connected Self” or spirit in the dream takes the role of therapist or teacher who has keys or permission to navigate between the dream world (spiritual domain?) and the physical world (semi-lucid awareness of being there in bed and in a body while experiencing the dream drama). I would like to think my main Self is working on the enlightenment suggested in that narrative (St. John?).
LOL, there's a lot of selves here!
I think I'm right in saying there's only one 'self' in Christian metaphysics, and I think the same applies to most traditional metaphysical systems. There are
states within the self, which is probably what you're referring to as 'selves', and one can, to a certain degree, move between states.
The simplest I can offer is the Pauline distinction between the 'psychical' and the 'spiritual' – a
sóma psychikon (σῶμα ψυχικόν) is flesh-and-blood
sarx (σάρξ) animated or given life by
psyche, the soul, and thus becomes a living body
sóma (σῶμα), whereas a
sóma pneumatikon (σῶμα πνευματικόν) is a body
sóma (σῶμα) that is constituted from and lives by the deathless spirit,
pneuma.
The point here, as St Paul tries to explain, is that they are one and the same
soma, one and the same
self, but that
self has been transformed, one might even say transfigured.
A way of speaking of the dead is to look at the cadaver of a person and say 'they are no longer there' – there is no
soma, no
self present, and to stretch the analogy one might say the
sarx is a body, but no-one's home. A lived-in body is a
self, a
soma. That
soma can be either a
psychikon or a
pneumatikon, but it's still the same, single self.
