Psychology: Dreams and Dreaming

January 13, 1997

Dreams, a nightly gift and a part of the natural process of being alive,

are being rediscovered by our publisher. The meaning and value of your dreams

will vary according to what you and your society decide. Our society is

changing. We used to only value dreams in the context of psychotherapy. There

are also a few assumptions about dreams. One is that you are always the final

authority on what the dream means. Others can offer insight, suggestions and

techniques for exploration and expression, but no one knows what the final

meaning and value of the dreams will be for you, except you. Another assumption

is that dreams come in the service of wholeness and health. If you find an

interpretation that does not fit this, perhaps you need to change methods of

interpretation. Dream interpretations that lead you toward self-criticism,

depression or despair are simply wrong and if these conditions persist you may

wish to seek help from others. Finally, there is no such thing as a dream with

one meaning. If you feel stuck on one meaning or feel another person is pushing

one meaning, it is time to reconsider your methods and approach. (Lemley p. 17).

Clinical dream work is done within the context of psychotherapy and

clinical and sleep research have different approaches and goals than peer dream

work. (Koch-Sheras p.16).

A dream is a period of spontaneous brain activity usually lasting from

about 5-40 minutes that occurs during sleep several times a night usually about

90 minute intervals (Barret p.8).

There are also certain types of dreams. There are fantasy, daydream and

waking dreams. There are also lucid dreams, nightmares and night terrors.

There are also certain stages in the dream cycle. In the first stage, your body

temperature drops, your eyes close and your brain waves begin regular alpha

rhythms, indicating a relaxed state. Muscles lose their tension, breathing

becomes more even and your heart rate slows. Second, random images begin to

float through your mind mimicking the dream state. Jolting or involuntary

movements will take place at this time. Third, muscles lose all tightness,

breathing becomes slower, heart rate decreases and blood pressure falls. At

this point, it will take a loud noise or disturbance to wake you up. You are

now fully asleep. Finally, you are in a deep sleep. This is the most

physically rested period of sleep and longest in duration. (Time-Life Books p.

97).

Whether awake or asleep, one of the brain’s most critical functions is

the construction of the model of the environment that we perceive as our

conscious experience (Barret p. 9). While we sleep, very little sensory input

is available, so the world model experience is constructed from what remains,

contextual information from our lives, that is, expectations derived from past

experience, and motivations. As a result, the content of our dream is largely

determined by what we fear, hopeful and expect. From this point of view,

dreaming can be viewed as the special case of dreaming constrained by sensory

input (Koch-Sheras p. 15). Dreaming experience is commonly viewed as

qualitatively distinct from waking experience. Dreams are often believed to be

characterized by lack of reflection and inability to act deliberately and with

intention. (Barret p. 20).

Although we not usually explicitly aware of the fact that we are

dreaming while we are dreaming, at times a remarkable exception occurs and we

become reflective enough to become conscious that we are dreaming. During such ?

lucid’ dreams it is possible to freely remember the circumstances of waking life

to think clearly, and to act deliberately upon reflection or in accordance with

plans decided upon before sleep, all while experiencing a dream world that seems

vividly real. (Time-Life Books p. 57).

As previously stated, lucid dreaming is dreaming while knowing that you

are dreaming. Lucidity usually begins in the midst of a dream, when the dreamer

realizes that the experience is not occurring in physical reality, but is a

dream. (Lemley p. 3). A minority of lucid dreams are the result of returning to

REM sleep directly from a awakening with unbroken reflective consciousness.

When lucidity is at a high level, you are aware that everything

experienced in the dream is occurring in your mind, that there is no real danger,

and that you are asleep in bed and will awaken shortly. With low level lucidity

you may be aware to a certain extent that you are dreaming, perhaps enough to

fly or alter what you are doing, but not enough to realize that the people are

dream representations, or that you can suffer no physical damage, or that you

are actually in bed. (Time-Life Books p. 58).

Lucid dreams usually happen during REM sleep. Research has been

demonstrated that most vivid dreaming occurs in REM sleep. It is characterized

by an active brain, with low amplitude, mixed frequency brain waves, suppression

of skeletal muscle tone, bursts of rapid eye movements, and occasional tiny

muscular twitches (Barret p. 20).

Jubera 3

The sleep stages cycle throughout a night. The first REM period

normally happens after a period of delta sleep, approximately 90 minutes after

sleep onset, and lasts from about 5-20 minutes. REM periods occur roughly every

90 minutes throughout the night with later REM periods occurring at shorter

intervals and often being longer, sometimes up to an hour in length. Much more

REM sleep occurs in the second half of the night than in the first. (Lemley p.

16).

Most of the muscles of the body are paralyzed in REM sleep to prevent us

from acting out our dreams. However, because the eyes are not paralyzed, if you

deliberately move your ?dream? eyes in a dream, your physical eyes move also.

(Time-Life Books p. 61 ).

Referring back to the stages in sleep-the first stage is a transitional

period between waking and sleeping known as hypnagogic state, the muscle relax

and the person often experiences a sensation of floating or drifting. The eyes

roll slowly and vivid images may flash through the mind-perhaps an eerie

unfamiliar landscape, a beautiful abstract pattern or a succession of face. As

those sensations and visions come and go, a sudden spasm of the body called

hypnagogic startle may momentarily waken the sleeper. Then as the subject slips

into the first stage of sleep, the EEG shows the spiky rapid alpha waves of a

relaxed but wakeful brain giving way to the slower more regular theta waves of

light slumber. Sleeps first stage is short, lasting anywhere from a few seconds

to 10 minutes. The theta waves soon decrease and are mixed on EEG tracing which

a combination of 2 different brain wave patterns-groups of sharp jumps called

spindles, which reflect rapid bursts of brain activity, and waves known as K-

complexes characterized by steep peaks and valleys. Although this stage is

considered to be a true sleep phase, a person awakening from it may report

having had brief bits of realistic thought or may even deny having been asleep

at all. (Time-Life Books p. 97).

Between 15 and 30 minutes after the onset of sleep, large, slow delta

waves begin supplementing the K complexes and spindles of stage 2. The change

makes the deepest of sleeps, called stage 3-4. Waking from stage 3-4 is

difficult. An individual typically feels quite groggy and disoriented and even

if an emergency demands alertness, must fight to overcome the compelling desire

to fall asleep again. Taking in one sleep, sleep walking and bedwetting tend to

happen during this stage because of the brain’s partial arousal from deep sleep

(Time-Life Books p. 97).

After 90 minutes or so of sleep, most of it spent in stage 3-4, the

spindles and K complexes of stage 2 briefly reassert themselves. The brain then

shakes off the rhythms of non REM sleep passes into REM sleep-a condition so

distinct physiologically from both wakefulness and the non REM stages that some

experts call it a third state of existence. Blood pressure and pulse rate rise,

and brain waves quicken to frequencies comparable to those of an awake, alert

brain. Despite this activity the body becomes remarkably still. The eyes begin

their movements, but otherwise, except for grimaces and small twitches of the

toes and fingers, the muscles are temporarily paralyzed. A person awakened from

REM sleep may be unable to move for a few seconds. Scientists believe that

nature has evolved this paralytic interlude, which seems to be controlled by

nerve centers in the primitive brainstem, to protect the sleeper from the harm

that might result if dreams were physically acted out. The 2 antithetical

conditions of the state-a vigorously active brain within an immobilized body-

prompted French neurobiologist Michel Jouvet to name it ?paradoxical sleep?.

(Time-Life Books p. 99).

There are other physical characteristics of dreams as well. In adults

and infants alike, the head and chin relax so completely that researchers can

use the slackening of the muscle under the chin as a reliable signal that REM

sleep is occurring (Lemley p. 19-20).

After training in neurology Sigmund Freud (1856-1939) began to practice

what later became a psychoanalysis. Initially, following his colleague Josef

Breuer ( 1942-1925), he used his hypnosis to treat cases of hysteria. He then

replaced hypnosis with the technique of free association and began to explore

his patient’s dreams for clues to their problems (Barret p. 14-15).

Freud believed that dreams were wish fulfillment-in our dreams we

represent our deepest desires, which in an adult are nearly always sexual.

However, because these desires would be offensive to our sleeping conscious

minds, or censor or superego, disguises our true intentions. The obscurity of

dreams, Freud said ?is due to alterations in repressed material made by the

censorship.? However this theory does not explain why we might have a heavily

disguised dream one night and a straightforward dream of the same activity on

another night. There are many problems with Freud’s ideas but he must be given

credit for being one of the first modern thinkers to reexamine the symbolism of

dreams. However he must also be criticized for seeing nearly every dream symbol

in purely sexual terms. Freuds detractors also complain that his theories ,

based on evidence drawn from his psychologically disturbed patients, were not

universally applicable. Despite these criticisms, Freud created psychoanalysis

almost single-handedly, and built a solid base for dream analysts to expand

(Barret P. 14-15).

Besides establishing the normal nightly course of dreaming and some of

its pathological aberrations, researchers have categorized 2 distinct but

equally frightening disturbances: the nightmare and the much less common night

terror (Time-Life Books p. 102). Everyone occasionally has a nightmare-a dream

so frightening that he or she wakes up sweaty, short of breath, and with a

pounding heart. Such dreams usually occur during the second half of the night,

when REM periods are longer and dreams are more intense. Psychiatrists such as

Stanley Palombo of Washington, D.C. , believe that a nightmare (mare means

goblin in Old English) dramatizes problems or anxieties one has recently

encountered in waking life, in addition, it evokes related unconscious memories

and images, creating an emotionally powerful mix. The feeling of utter

helplessness that so often infuses a nightmare probably harks back to infancy,

some experts say, when a child is indeed powerless and at the mercy of a world

he or she cannot understand or control. ( Time-Life Books p. 102).

According to Professor Hartmann, ?the common thread among those who have

nightmares frequently is sensitivity.? For a Boston study, he solicited

volunteers who experienced nightmares at least once a week. A large number of

subjects were involved in creative work, such as art, music and theater, others

were graduate students, teachers and therapists. (Time-Life Books p. 106). Many

saw themselves as rebels or as ?different from other people,? and some overly

rejected society’s norms. ?They were all very open and vulnerable?, he said,

beneficial to their careers. But ?most had had stormy adolescence sometimes

followed by bouts with depression, alcohol and suicide attempts?. Hartmann

concluded that people who had frequent nightmares possessed a poor sense of

their own identities and find it hard to separate fantasy from reality. Some

have borderline or potentially psychotic tendencies, he believes. (Time-Life

Books p. 106).

Night terrors differ from nightmares in both content and timing, and

often occur in a deep slumber of stage 3-4. The sleeper may rouse with a blood

curdling scream and sit up in bed, terrified and confused, heart racing. (Time-

Life Books p. 106). He may also walk or talk in his sleep. While people

usually remember specific and sequential details of their nightmares, the victim

of a night terror is short, lasting only a minute or 2. Night terrors seem to

run in families, and researchers suspect they are triggered by a faulty arousal

mechanism: instead of following the normal shift early in the night from stage

3-4 sleep to a REM period, the sleeper partially rouses. Children are more

susceptible than adults to night terrors, perhaps simply because they spend more

time in stage 3-4 (Time-Life Books p.106).

Message dreams are dreams that convey some information you need about

your current social, emotional or physical life. These are teaching dreams in

which someone is usually there to tell you something important directly: a

teacher, a news announcer or clergyman giving you new information to apply to

your waking life. At times, a message dream will come in the form of a

disembodied voice; the dreamer may perceive this voice as a voice of the spirit

or soul of God or an angel (Koch-Sheras p. 78).

Recurring dreams repeat themselves with little variation in story or

theme. They can be positive, as with an archetypal visionary dream, but they

are more often nightmares, perhaps because nightmares depict a conflict that is

unresolved; also nightmares are more frequently remembered than other dreams.

(Lemley p. 81).

There are many reasons why people forget their dreams upon waking. In

our culture, and therefore in our families, dreams are generally thought of as

unimportant or silly. Whether they are pleasant or unpleasant, your dreams are

a vital and expressive part of yourself, so don’t discount them! Another reason

why people might forget dreams is that they are embarrassed by their content.

In dreams, you might commit acts you would never do in your waking life, and it

is natural to put those acts into the back of your mind rather than confront the

issues the dream scenarios might have raised. (Koch-Sheras p. 113). Studies

show that people who are good at recalling their dreams are generally better

able to confront their own fears and anxieties; poor dream recallers are those

who tend to retreat from confrontation. Learning to remember your dreams and

discuss their meanings may help you to become a more assertive person (Koch-

Sheras p. 113).

If you yourself are a poor recaller, you may wonder who images manage to

stow away in a person’s mind each morning. The fact is, people who enjoy

sharing dreams are more likely to remember them. Any attention you pay to your

dream life can help to increase your recall: keeping a dream journal, making a

drawing based on a dream, acting on advice or insight gained from a dream

(Lemley p. 113).

In ancient times, dreams were often-but not always-believed to be

prophetic, and people of all cultures shared what they had dreamed in hopes of

catching a glimpse of the future or receiving a message of advice or warning

(Lemley p. 26). The Egyptians, for instance, relied on an elaborately

constructed list of interpretations, a kind of early dream dictionary. Even the

ancient Greek philosopher Socrates considered dreams to be prophetic emanating

from the Gods. For this reason, dreams figured prominently in ancient cultures’

religious rituals intended to evoke the dream spirits of Gods who would send

these vivid messages ( Koch-Sheras p. 26).

In many ancient cultures, dream life and waking life were simply 2

different dimensions of a single existence, a viewpoint that shows itself in
