An article I came across which, although not entirely Jungian in nature, does support the above.

... In our book, Human Givens: A new approach to emotional health and clear thinking, we described how the REM brain state, which underlies dreaming, is separate from the process of dreaming and dream content. It is also clear that the healthy brain is organised to keep the dream process separate from the waking state, which is why we find it so difficult to remember dreams. We have shown how the behaviour of a person in a hypnotic state clearly mirrors phenomena of the REM state, such as muscle paralysis, dissociation, imperviousness to pain, and amnesia for the event after "waking".

A psychotic breakdown is almost always preceded by an overload of stress and severe depression in a person's life, which, as we know, results in excessive REM sleep. We are now convinced that, when people are in psychosis, they are in fact trapped in the REM state, a separate state of consciousness with dreamlike qualities. In other words, schizophrenia is waking reality processed through the dreaming brain.

... In the dream state, which is the province of the right hemisphere of the brain, people are not usually capable of independent thought, the province of the left hemisphere, because the mind is "locked" into the metaphorical script of the dream. But if an individual is trapped in a waking REM state, with waking reality happening around them, there is still likely to be activity in the left hemisphere of the brain.

We suggest that, because the REM state operates through metaphor, the only way it could make sense of these independent left brain thoughts would be to create the metaphor of hearing voices, or being watched, or spied upon by "aliens" which easily becomes paranoia. ...

Rapid eye movements are often seen to occur in psychotic states, which, of course, are the defining sign of the REM state. Psychotic patients also very quickly convert thought into sensory experience, with the result that they can become highly emotional almost instantly. When recalling a distressing memory, for example, they can be instantly transported right back into that memory and re-experience the emotions connected with it. That phenomenon, too, is a characteristic of the dream state, when arousals from the emotional brain trigger a thought pattern, in the cortex, which is immediately converted into a sensory metaphor -- the dream.

It is not surprising, then, that psychotic patients not only talk in metaphors but live them out, which explains their often bizarre speech and behaviour. ... We suggest that we can use this insight to help people make sense of their psychotic experience. Ordinarily, there is ongoing interplay between the left and right hemispheres of the brain. ...

In our preliminary investigations, using these concepts, we have found that psychotic patients calm down when they realise there is an explanation for what is happening to them. When calm, the psychotic phenomena become less threatening and less intense. Then we can start doing what many traditional third world countries seem to do so much better -- re-orientating people towards getting their emotional needs met and creating strong support structures for them.
