One more thought relating the above theory back to Schizophrenia. If
the above theory holds, then associating a full overloaded brain to be
the reason behind Schizophrenia may not be the correct explanation.
Rather the same "hormones" responsible for chemically sparking activity
of "weak" garbage neurons in a dreaming state might be active when
Schizophrenic patients are awake.

I know that one pill was accidently found I think in the 60s that works
to stop Schizophrenic symptoms without anyone really knowing the reason
how the pill works. Perhaps that pill simply blocks that specific
hormone from producing the chemicals responsible for activating
the "weak" neurons for cleanup purposes that normally occurs during the
dreaming process.

In any case, Schizophrenia is related to extream stress so the brain
might be reacting with a protective cleanup reaction to the overload
taking place. Dreams are just hallucinations, we are all Schizophrenic
when we are dreaming during sleeping.
