Re: Fwd: Auditory hallucinations

Dear List,

I passed the email at the end from Al Bregman on to Freud scholar Simon
Boag, who replied as follows.

        Harvey Holmes

The mentioned hypothesis is an old one and to some extent is a cornerstone
of Freud's thought. More recently, Hobson, who is anti-Freud, has expressed
similar ideas. You'll find a summary of his views in:

Hobson, J. A. (2004). A model for madness? Dream consciousness: Our
understanding of the neurobiology of sleep offers insight into
abnormalities in the waking brain. Nature, 430, 21.

Dear Sukhi,

I think there are two reasonably close analogs of schizophrenic
1.  Dreaming during normal sleep.
2.  The hallucinations that one can induce in awake people via
        (a) long periods of sensory deprivation
        (b) depriving normal people of the opportunity to dream during
              by waking them up whenever they start to dream.

For some time, I have entertained the idea that the hallucinations in
schizophrenics were a disorder of the normal dreaming mechanism.  Why don't
we dream during the day?  Some mechanism must suppress it.  Maybe this
suppression mechanism is defective in schizophrenics, or requires that
external events engage a much higher level of interest (or arousal) before
it kicks in.

Best wishes,
