Dopaminergic drugs can do the same thing. Although some patients
who take dopaminergic drugs for Parkinson’s disease develop devastat-
ing compulsions, others experience enhanced creativity. One patient
who came from a family of poets had never done any creative writing.
After starting dopamine-boosting drugs for his Parkinson’s disease, he
wrote a poem that won the annual contest of the International Asso-
ciation of Poets. Painters treated with Parkinson’s medication often
increase their use of vivid color. One patient who developed a new
style after being treated said, “The new style is less precise but more
vibrant. I have a need to express myself more. I just let myself go.” Just
like Winnie-the-Pooh: “It is the best way to write poetry, letting things
come.”
DREAMS: WHERE CREATIVITY
AND MADNESS MINGLE
Few of us are geniuses or madmen, but we have all experienced the
midpoint on this continuum: dreams. Dreams are similar to abstract
thought in that they work with material taken from the external world,
but they arrange the material in ways that are unconstrained by phys-
ical reality. Dreams often contain the theme of up, such as flying or
falling from a great height. Dreams often involve future themes, too,
sometimes in the form of the pursuit of some intensely desired goal
that’s always just out of reach. Abstract, detached from the real world
of the senses, dreams are dopaminergic.
Freud named the mental activity that takes place in dreams “pri-
mary process,” which is unorganized, illogical, created without regard
to the limitations of reality, and driven by primitive desires. Primary
process has also been used to describe the thought process seen in peo-
ple with schizophrenia. As the German philosopher Arthur Schopen-
hauer wrote, “Dreams are brief madness and madness a long dream.”
Dopamine is unleashed during dreaming, freed from the restrain-
ing influence of the reality-focused H&N neurotransmitters. Activity in
the H&N circuits is suppressed because sensory input from the outside
129
CREATIVITY AND MADNESS
world into the brain is blocked. This freedom allows dopamine circuits
to generate the bizarre connections that are the hallmark of dreams.
The trivial, the unnoticed, and the odd can be elevated to positions of
prominence, supplying us with new ideas that otherwise would have
been impossible to discover.
The similarity between dreaming and psychosis has fascinated
many researchers, and has spawned a rich scientific literature. A group
from the University of Milan in Italy looked at the presence of bizarre
thought content in the dreams of healthy people, and compared
them to waking fantasies of both healthy participants and those with
schizophrenia.
Scientists stimulated waking fantasies

using the Thematic Apper-
ception Test (TAT), a series of cards showing ambiguous, sometimes
emotionally charged pictures of people in various situations. Themes
include success and failure, competition and jealousy, aggression, and
sexuality. The participant is asked to study the picture, then make a
story explaining the scene.
The Italian researchers compared the TAT stories and the descrip-
tions of dreams of patients with schizophrenia to those of healthy com-
parison participants using a scale called the Bizarreness Density Index.
The results of the tests confirmed that dreams are very much like psy-
chosis. The Bizarreness Density Index was almost exactly the same for
three categories of mental activity: (1) the descriptions of dreams of
people with schizophrenia, (2) the waking TAT stories of people with
schizophrenia, and (3) the descriptions of dreams of healthy people. On
the other hand, the fourth category, waking TAT stories of healthy peo-
ple, scored much lower on the index. This study supports Schopenhau-
er’s conception that living with schizophrenia is like living in a dream.

fantasy
refers broadly to the products of the imagination, rather
than the more common use to signify daydreams of things like unlimited wealth.

HOW TO HARVEST CREATIVITY FROM A DREAM
If dreaming is similar to psychosis, how do we get back to our normal
selves? Does it happen all at once, or does it take some time to restore
logical thought patterns? If it takes time, are we a little bit insane while
the transition occurs? Here’s something else to consider: sometimes
when we’re asleep we dream, and other times we don’t. As we make the
transition from sleep to wakefulness, is our thought process different if
we are waking from a dream or from dreamless sleep?
Researchers at New York University used the TAT to evaluate the
kinds of stories people produced after they were woken from dream-
ing sleep and compared them to TAT stories produced after they were
woken from non-dreaming sleep. They found that fantasies produced
immediately after dreaming were more elaborate. They were longer,
and contained more ideas. The imagery was more vivid, and the con-
tent was more bizarre. Here is an example of a story given by a healthy
volunteer after being woken from a dreaming state. The volunteer was
shown a picture of a boy looking at a violin:
He’s thinking over his violin. He makes a sad impression. Wait
a minute! He’s bleeding out of his mouth! And his eyes . . .
seems like he’s blind!
Another volunteer who had been woken from a dream was shown a
picture of a young man, slouched on the floor, his head resting on a
bench. There is a pistol on the floor next to him. Here is the response:
There is a boy in a bed. He may be having some kind of
emotional problem. He is nearly crying, or it may be he’s
laughing, maybe having a game. It could also be a girl.
They’re both dead. Or maybe it’s a cat? There is something
on the floor . . . keys, a flower, or maybe it’s a toy, or a boat.
After being woken from a non-dreaming sleep, this same participant
was shown another card, and wrote a notably less bizarre description,
131
CREATIVITY AND MADNESS
stating simply that it was “a boy wearing a shirt, who doesn’t have any
socks on. I don’t see very much else.”
Many people have had the experience of waking from a dream, feel-
ing as if they were caught between two worlds. Thinking is more fluid,
making leaps from topic to topic, unconstrained by the rules of logic. In
fact, some people report that they experience their most creative thoughts
in this crack between the two worlds. The H&N filter that focuses our
attention on the external world of the senses has not yet been reengaged;
dopamine circuits continue to fire unopposed, and ideas flow freely.
