One [or more - I've started this reply to do one thing,
but might find something else that can use a 'tweak]
CLARIFICATION[s] added below.

It's because this whole-experiential-total cross-correlation, that can
only occur during the special "supersystem configuration" [AoK, Ap5]
that is "sleeping-consciosness", does, in fact, occur during sleeping-
consciousness, that the whole of one's experiential total is, in fact,
more or less [see below] 'present' 'within' ['underneath'] this or that
'momentary' waking-consciousness information-processing.

[The "more or less" qualifier is necessary because these dynamics
occur as a function of the 'level' at which the "volitional diminishing-
returns decision" threshold [AoK, Ap7] is 'set'. That is, one can
volitionally 'choose' the degree of experiential-total cross-correlation
that one wishes to achieve. Hence, the "more or less", in the paragraph
above. In many ways, the 'passion' that's evident in the way I endeavor
to communicate NDT's understanding derives in seeing how much of
the harm that folks experience derives in folks' "volitional diminishing
returns decision" thresholds being 'set too low' - which results in commen-
surately-less of this experiential total cross-correlation. When I 'jump
up and down', it's usually the case that I'm working to give folks'
"diminishing returns decision" thresholds a little 'lifting-up' - which, for
those who grasp the 'moment', is a 'Gift' of being able to Think more-
deeply. I Love folks in that way. But folks are Free to Choose with
respect to such. It's be-cause I've been aware of all of this all along
that I, long ago, called myself to task with respect to the Necessity
of Guarding Free WIll. I do. It's not 'manipulation', because folks
are Free to Choose. For those who do so Choose, it's about the
best Gift that can be received. It literally is a Gift of being able to
'move toward' Truth - to See Truth, ever-more-clearly. I Love folks
in that way. Learned such from Jesus.]

One does a crude version of this stuff whenever one "defragments" the
hard disk on one's computer. [I always do defrags in a stand-alone way
[while not, otherwise, using my computer], because I like to think about
what my computer is doing in this 'sleep state' :-]

BTW, any 'AI' system =must= have an analogue of "sleep" - for the
reasons discussed above. Doing it 'in the background' unacceptably
degrades 'foreground' processing in a real-AI thing. [Forground
processing =must= grasp as much as the 3-D energydynamics that
are occurring in it's experiential environment as is possible - if it is,
in fact, to approach real-AI. I wish Microsoft[tm] would learn this, and
not ab-use 'foreground' processing by imposing so much 'background'
processing upon it in their 'OS' engineering. Where they see 'unused
clock cycles', I see only the information-processing capabilities of my
PC, and I want to use them for what I want to do, not what someone
else wants to do with them. Windows XP[tm] is 'background' processing
run amok.]

That's all for this clarification.
