I understand your question. There are other threads that address the extent of the detailed explanation (development) and use of metaphors as well as Tom's videos regarding your point. Tom describes and develops the concept of consciousness from the "top down" and generally the policy of the forum is to stop at the IUOC in that explanation. You can go through my posts around 3 months ago and find the links and quotes, etc. Here is my best effort to explain it.
Then, here is my question.
Here and now, “I”, the particular subset of the IUOC that is logged in this datastream and that I play now, is separated from the main IUOC. I mean I am conscious of my particular environment and the IUOC is also conscious, separately, of his environment in the NPMR. Both are “conscious” in the same time. 2 “consciousness”.
Theoretically there is no separation. There is one consciousness. The "I" consciousness is self aware: is the IUOC, FWAU and "I" avatar, etc. These are metaphors designed to explain but once you advance you drop the metaphors. It is helpful to understand the OOBE experience too. The "I" avatar is self aware as part of the rule set. It is not aware of the true nature of reality.
When the avatar in which the “partition” that “I” am right now will die, boundaries will be taken down and “I” will reintegrate my IUOC. But Tom says that in that process, the “FWAU partitioned” will disappear, because “I” will reintegrate the IUOC that has his own FWAU
When the avatar dies the "I" FWAU consciousness (formerly the partitioned avatar consciousness), depending upon its entropy, becomes self aware of the true nature of reality. "I" then goes through a transition as an FWAU with the memory, personality of the avatar's life experience. Time no longer is part of the rule set.
Then, logically, should we consider that when the boundaries are taken down, “I” will lose the conscience I have of my self to the benefit of the FWAU of my main IUOC?
I mean, is there a “continuity of consciousness” regarding the consciousness of the FWAU partitioned?
No, you are aware of self and that awareness is the same in the FWAU. This is the waking state referred to in an OOBE. The Avatar is a vessel for consciousness to experience objective reality. There is a continuity of consciousness during the transition as the FWAU. The "I" avatar self awareness becomes the "I" FWAU self awareness but is now aware of the true reality of its existence.
How can “I” still be aware of myself if my FWAU disappear?
Once the FWAU disappears the "I" self awareness (free will) resumes as one consciousness as an IUOC. The "personality" of that life experience (devoid of free will) becomes a part of the actualized past data base (akashic record).
