I agree. Still we must find some common basic agreement for being
able to talk about those levels.

Have you seen "the thirteen floor". It's a movie based on
Simulacron 3. Unfortunatley it appears at the same moment than MATRIX.
The ideas are also very difficult to render through a movie.

Well, I think you can say space-time is an illusion when:
1) When you feel it and you say that to yourself, but in that case I think
poetry is more appropriate, like Lewis Carroll writing :"life, what
is it, but a dream".
2) When you give a description of the "one" which is illusioned and
in what sense there is an illusion of space-time. (Like when we say
that in a movie there is an illusion of movement).

I will think about your graphic, at first sight there is conflict!
(Hopefully not linguistic conflicts).
