Military personnel returning from wars in Afghanistan and Iraq show increasing rates of post-traumatic stress disorder (PTSD) and post-traumatic nightmares. Media coverage of these two vexing mental health conditions is also intensifying and raising public awareness about the need for more effective therapeutic options. With growing attention focused on patients with nightmares, sleep centers have an opportunity to engage these patients. Successfully doing so hinges on applying a standard of care for nightmare assessment and treatment through behavioral sleep medicine specialists.

MENTAL HEALTH VIEW OF NIGHTMARES

Traditionally, nightmares reflect emotional turmoil that needs venting through the process of dreaming. This psychological perspective fuels the entrenched and enduring focus on dream interpretation therapy as one of two core treatments for this potent sleep disrupter. The other primary approach known as exposure therapy is gaining ascendency in the mental health community because of the prevailing view that PTSD—the cause of the disturbing dreams—must be treated first. As the theory goes, the nightmares will resolve when their cause is treated. Yet, both these treatment paradigms (dream interpretation and exposure) trigger treatment avoidance among nightmare patients because of their fear of unmasking unpleasant mental health issues. Although this paradox creates an opening for nightmare patients to seek help outside of mental health facilities, it is rare for sleep medicine clinics to encounter patients seeking treatment exclusively for nightmares.

“He was stuck on the needle,” says Deirdre Barrett, psychology professor at Harvard Medical School. He couldn’t get it through fabric and bring thread back again.

Then he had a frightening dream of island savages threatening to spear him if he didn’t finish the design. He awoke excited, because their spear tips had holes — like needles with eyes in the point — and the solution to his problem.

Our life is influenced by dreams whether we like it or not, says Barrett, author of “The Committee of Sleep.” But she and other experts say dreams can be harnessed to solve problems (especially when we have to think visually or out of the box) and increase our emotional intelligence.

Our sleeping minds took the spotlight this summer as the film “Inception” grossed $283 million at the box office and asked us to wonder if someone else could change our behavior by entering our dreams.

Most of us think of dreams as stories that help process waking life, says Dr. Barry Krakow, medical director of Maimonides Sleep Arts & Sciences in Albuquerque.
While science can’t say for sure, Krakow, author of “Sound Sleep, Sound Mind: 7 Keys to Sleeping Through the Night,” says he believes that’s true. “Life is multidimensional,” Krakow says. It would be impossible to consciously understand all of it — work, family, society — as a single unit. But “dreams have that capacity to integrate thoughts and images.” And dreams often do more than merely echo waking life, Barrett says. She points to past studies showing that, while bad dreams often follow bad days, it’s frequently the other way around. Our days often mirror dreams from the night before. “I think dreams do set the emotional tone for the day,” says Thomas McKenna, who does dream therapy at Life Change Psychotherapy Institute in Albuquerque. “Sometimes it’s more subtle,” he says, less a direct link than an “emotional coloring.”

Human Intelligence

Human intelligence, as everyone knows, is a complex dimension to measure, and I am no expert in measuring it. However, as a sleep doc, I’ve formed some fairly clear perceptions about patients with insomnia, who I believe often ‘suffer’ from a higher than average level of ‘intellectual’ intelligence, for lack of a better term.

TFI System

This insight emerged in my own thinking once I realized that most human behavior is coupled to a fairly prominent system of consciousness called the TFI System. (T = Thoughts; F = Feelings; and I = Images.) I write extensively about this system in my book, Sound Sleep, Sound Mind, because the balance within any individual’s TFI system predicts who is most likely to suffer insomnia, who is most likely to have difficulty adjusting to PAP therapy, and who has the capacity to engage in sufficient, self-generated cognitive restructuring (‘changing your mind’) to overcome or adapt to either of these difficulties (insomnia or PAP issues).

To simplify, before you eat, you THINK about the need or desire for food, FEEL hungry for food, or PICTURE (IMAGE) in your mind’s eye the sumptuous Caesar salad you crave. Each of these three activities represents the unique and overlapping components of the TFI System. If you spend time ‘observing yourself’ throughout the day, you will notice you spend at least some time with each component preceding, during or after various behaviors.

In unusually well-adjusted individuals, great awareness of all 3 components is the norm, leading to a balanced system in which the individual freely moves through all components at any given time as needed to adapt to and interact with their environment and the people in it. Having said that, you can no doubt imagine a hundred interpretations of what a ‘balanced system’ entails or feels like. Without wishing to be cryptic, however, let me just say that tasting the experience of a balanced TFI System is a much easier way to know it than someone trying to explain it to you.

Lacking Balance in the TFI System

It’s much easier to explain the opposite’a lack of balance, in which one component of the system tends to predominate or one component tends to be relatively absent. Most of us learn to keep our TFI systems out of balance, and we usually adopt this jaded system some time in childhood or adolescence. As the most classic and relevant example to our discussion, many insomniacs show a high intellect that arguably developed out of a desire (usually unplanned) to adopt an imbalanced system dominated by thoughts and lacking in emotion, which turns out to be a perfect setup for insomnia.

Let’s assume you are a smart person, and your intelligence is obvious to those around you as early as childhood. More importantly, let’s suppose you begin to notice in school or elsewhere that your mind is sharper or quicker than many others at certain intellectual tasks: solving math problems, remembering grammar rules, knowing more words, how to spell them and what they mean and so on. In a short time, you would receive a great deal of reinforcement (grades, praise, requests for advice/answers, etc.) buttressing the belief that your ‘thinking capacity’ is more advanced than others. Very soon, you will turn repeatedly to your powers of intellect to solve the problems you face. So far so good; this example describes a fair number of people who end up with graduate degrees in engineering, physics, medicine, other sciences and so on. In these individuals, ‘Thoughts’ are the predominant component of the TFI system and up to a point have served them well in society.

The question or problem arises at some point as to what happens to the other two components of the system: Feelings and Images. The answer for a lot of individuals is the person grows far too comfortable solving life’s problems with thoughts and conversely grows more uncomfortable attempting to manage emotions or mental imagery. Why so? Because the latter two components of the TFI system seem or feel chaotic; whereas, thoughts seem more controllable.

Over time, some individuals who go down the intellectual path will see a decay in their innate capacity to work effectively with feelings and mental imagery. In the single most classic example of this phenomenon, individuals no longer readily access their own emotions in direct fashion. Instead of ‘feeling their feelings,’ they ‘think about their feelings.’ If you describe this distinction to someone with a healthy and balanced TFI system, they immediately and fully understand the difference. If you make this point to an insomniac, they often need much more explanation (still more intellectual discussion) just to come close to understanding the distinction between ‘thinking about vs. feeling an emotion.’

Insomnia and the TFI System

And, therein lies the basis of my observations and theories. In my clinical and personal experience, people with balanced TFI systems rarely have trouble closing out the day at bedtime. Because they’ve spent much of the day processing a wide array of thoughts, feelings, and images, they fall asleep faster than you can say ‘lights out.’ But, for the individual with too much reliance on intellect, the lack of balance throughout the day means that emotional or imaginative residue probably lingers at bedtime and prevents the necessary closure that leads to the Land of Nod. In fact, among the majority of insomniacs, the single most common complaint is ‘I cannot turn off my mind,’ which means racing thoughts or other ruminations actively fuel the mind with too much alertness to permit sleep.

Returning now to the balance concept, the intellectually inclined individual has spent far too much time in life developing their ‘thinking smarts’ but now they pay for it with insomnia. Why would too much thinking lead to insomnia? Because thinking represents a very active component of consciousness within the TFI System, whereas feelings and imagery represent more receptive components.

When you fall asleep, can you guess which components are closer to the final point of wakefulness where sleep onset begins? The answer appears to be feelings as in feelings of comfort and sleepiness, followed by mental imagery as in little dreamlets that flash across your mental landscape just as you fall asleep.

In other words, active thinking is antithetical to sleep; but if you spend more of your day in the world of thought, there is no easy way to turn off the spigot of thoughts at bedtime. In my book, I describe at length how excess thinking in most insomniacs has actually become a ‘defense’ mechanism, which individuals use to avoid feelings and imagery. But, as I’ve just pointed out above, sleep does not follow from an active and ruminating mind; it follows from a receptive mind based on comfortable feelings and dreamy images.

Summing Up

Most insomniacs I’ve treated have a marked imbalance of the TFI System. The thinking system is so powerful it blocks most feelings and some images throughout the day. Eventually, it prevents the individual from fully processing the day’s experiences, because the system directs the person to think and self-talk about the day without processing deeper emotions or clearer images about the actual experiences during the day.

Finally, SDB patients with similar or other imbalances of the TFI System tend to have greater difficulty adjusting to PAP therapy, because the imbalance makes their personality somewhat more rigid. Their ability to ‘change their minds’ and adapt to the foreign nature of PAP therapy is less than it could be if their minds were more balanced.

In sum, in a large proportion of insomnia patients and some proportion of poorly adapting PAP therapy patients, I routinely see this highly intellectualized intellect, which in fact frequently correlates with a higher IQ. In my opinion, these patients ‘suffer’ a great deal from this lack of balance as they try to solve their sleep problems.
