I remember reading some description of the stages of childhood intellectual development where the final stage was defined as the ability to understand hypothetical scenarios, and was shocked that something like 40% of people never reach that stage. I still question the percentage that was mentioned, but that the percentage is non-trivial explains why the response to "if such-n-such had happened then..." is often "but such-n-such never happened!". In fact, I seem to recall such non-arguments were used to illustrate this final stage.

Anyway, your conscious-of-consciousness description sounds a lot like the same kind of processing that goes into hypothetical scenarios, and your definition of consciousness might exclude a goodly number of adult humans.
