There are many ZAM-type models, which work very well for a long time. But, as
the person ages, some of them cannot meet the requirements due to the changes
in the internal parameters of the execution organs (legs, hands etc).
Such models self-activate during sleep (this is a premonitive-type dream) and
find that they don't meet the requirements anymore. This result can activate
the PSM too and produces the wake-up. The contents of such dreams is important
but, unfortunately, it is difficult to make the difference between a wake-up
dream and a premonition dream. Anyways, a premonition dream has to be taken as
a serious warning.
The dreams are associated with the technological implementation of the brain.
MDT, as a fundamental theory, cannot go beyond a limit. What was presented
here has to be considered just an evaluation of the dream problem.
