If you are attending a science fair in your dream, this suggests innovative thinking and possibilities. A scientific experiment in your dream signifies the need to consider your options and decide whether or not you want to move ahead with a particular plan. It may be suggesting that you need to adopt a reasoned and impartial approach to a challenge in your waking life.
If you find yourself busy inventing something in a laboratory in your dream, this suggests intellectual exploration and creativity.... The Element Encyclopedia
The next leap forward in understanding came when Aserinsky and Kleitman found rapid eye movements (REM) in 1953. In 1957 the REM were linked with dreaming. This defined sleep into two different observable states, REM sleep, and NREM (non-rapid eye movement or non-rem) sleep. Within NREM three different stages have been identified. These are defined by the different EEG patterns of electrical activity in the brain. They are measured by the height (amplitude) of the brain waves and frequency of up and down movement. There are also electrical changes occurring in the muscles (measured using an electro- myograph or EMG), and in movement of the eyeballs (measured using an electro-oculograph or EOG).
While awake the height is low and frequency fast. As we relax prior to sleep the EEG shifts to what are called alpha waves, at 8 to 12 cps (cycles per second). Stage one of sleep is the transition between this drowsy state of alpha waves to sleeping, in which theta waves occur, at 3 to 7 cps. In this first stage we experience random images and thoughts. This lasts about 10 minutes, followed by stage two, in which ‘sleep spindles’ occur which have 12 to 14 cps on the EEG. These last from 1/2 to 2 seconds, with K complexes following, which are slow large EEG waves. About half our sleep period is spent in this second stage of sleep. Deep sleep is reached when our brain exhibits delta waves, with 1/2 to 2 cps.
After approximately an hour and a half from falling into deep sleep, an exciting change occurs. We return to level two and REM occur. Suddenly the brain is alert and active, though the person is asleep and difficult to wake. This level has been called paradoxical sleep because of this fact. Voluntary muscular activity is suppressed and the body is essentially paralysed. Morrison has pointed out that, although the brain is transmitting full muscular activity messages, these are usually suppressed by an area of the brain in the pons. But bursts of short actions occur, such as rapid eyeball jerks, twitches of the muscles, changes in the size of the pupil, contractions in the middle ear, and erection of the penis. It may be that similar excitation occurs in the vagina. Also, autonomic storms’ occur dunng which large erratic changes occur in heart rate, blood pressure, breathing rate and in other autonomic nervous system functions. These are the changes accompanying our dreams.
If we slept for eight hours, a typical pattern would be to pass into delta sleep, stay there for about 70 to 90 minutes, then return to stage two and dream for about five minutes. We then move back into delta sleep, stay for a short period and shift back to level two, but without dreaming, then back into level three.
The next return to stage two is longer, almost an hour, with a period of dreaming lasting about 19 minutes, and also a short period of return to waking. There is only one short period of return to stage three sleep which occurs nearly four hours after falling asleep. From there on we remain in level two sleep, with three or four lengthening periods of dreaming, and returns to brief wakefulness.
The average amount of body shifting is once every 15 minutes.
1- In undergoing 205 hours of sleep deprivation, four healthy males showed various physiological and psychological changes. Some of these were headache, lack of concentration, hallucination, memory loss, tremor and, in some, paranoia. In all cases one night’s sleep restored normal functioning.
2- One in ten people who complain of excessive daytime drowsiness suffer from sleep apnoea, which is a stoppage of breathing while asleep.
3- A condition called narcolepsy causes sufferers to fall asleep at inappropriate times—while making love, walking, playing tennis, working.
4- As we age we usually sleep less. Our REM sleep in particular decreases sharply. ... A Guide to Dreams and Sleep Experiences
This general interpretation is reinforced by the well-known expression ’to reach for the stars’—or to strive to achieve your ambition—and if your dream focused on one particular star or plant, your dreaming mind may have been attempting to bring your aspirations to your attention. The sun, the moon and the stars are traditionally thought to influence a person’s destiny and, according to Western astrology, the Zodiac sign under which you were born, derived from the position of the stars and planets at the time of your birth, is thought to influence your character and the direction of your life.
Jung associated different archetypes with specific planets and believed that birth charts would generate archetypal images telling him something about the subject of the chart. He frequently looked at the birth charts of his patients with the assumption that the symbols in the charts made suggestions to him from the collective unconscious about that person’s psyche. Whether you believe in the principles of astrology or not, your unconscious may have tapped into these ancient associations, which is why it is always worth considering them when interpreting your dreams.

As we have seen, both Freud and Jung had theories regarding nightmares: Freud tried to explain them as the expression of unfulfilled wishes, whilst Jung described them as part of humankind’s ‘collective unconscious’ and argued that the helplessness we feel in nightmares is a memory of the fears experienced by primitive peoples. Today, in medical textbooks, nightmares are most commonly defined as a disturbing dream that results in at least a partial awakening.
Nightmares, in common with most dreams, occur during REM stages of sleep and they generally cause the dreamer to wake up.
If you don’t wake up, the dream is not technically a nightmare and could be described as a bad dream. Nightmares are often characterized by the following symptoms: a sense of fear and dread that lingers for hours or days after the dream upon awakening; the ability to recall all or part of a dream scene; in most cases the dreamer is threatened or actually harmed in some way; a recognition of powerful images in the dream or the repetition of the dream itself for months or even years after; and a physical paralysis or lack of muscle tone called atonia which signifies REM sleep.
Drugs, alcohol, lack of sleep and spicy food can alter the quality and quantity of REM sleep and perhaps trigger nightmares but there is no hard evidence to support this. Whilst these things can increase the risk of nightmares, the mundane struggles in daily life are generally thought to be the cause of most nightmares. Sleep researchers have discovered that long-standing nightmare sufferers tend to be emotional, creative, sensitive but prone to depression.
Modern sleep researchers have identified the following causes for nightmares:
• Unconscious memory of intense emotions such as that of a child being abandoned by its mother. Many people have had the experience of feeling trapped in a difficult situation—a terrible marriage or another situation they want to get out of—and nightmares can hark back to that situation, mirroring the intense feelings of being trapped associated with it.
• Intense experiences produced by external situations, such as involvement in war or being a victim of assault. Trauma, surgery, a death in the family, crime and accidents can also cause them to proliferate.
• Many nightmares in adults arise from fears connected with repressed internal drives or from fears concerning the process of growth and change.
• Threats to self-esteem. People may be faced by or fear the loss of something important to them, such as the failure of a relationship or the loss of a child, being seen to fail at work or not being able to cope with life in other ways. Nightmares may arise out of feelings of inferiority or loss of self-confidence.
Some sleep researchers consider the occasional nightmare to be a natural response to stress; the dream is seen to be the body’s way of practicing its ‘fight or flee’ response, providing us with a way to work through aggressive feelings in a safe way, given that the body’s muscles are essentially paralyzed during REM sleep....

Freud, who greatly influenced the field of psychology, believed dreaming to be a ’safety valve’ for unconscious desires, but it was not until the 1950s that scientists were able to study sleep and dreaming and come to some of their own conclusions.
In 1953, Eugene Aserinsky of the University of Chicago noticed that the eyes of sleeping babies moved beneath their eyelids at certain regular intervals. This led to the discovery of REM (rapid eye movement) sleep periods, which occur at roughly sixty to ninety minute intervals throughout the night, and contain the dreams that are the most vivid and most often remembered. Since then, EEG recordings that monitor brain activity during sleep have been used to map the various stages of sleep. Scientists soon realized that the strange, illogical experiences we call dreams almost always occur during REM sleep. Whilst most mammals and birds show signs of REM sleep, reptiles and other cold-blooded animals do not. REM sleep begins with signals from an area at the base of the brain called the pons. These signals travel to a brain region called the thalamus, which relays them to the cerebral cortex—the outer layer of the brain that is responsible for learning, thinking and organizing information. The pons also sends signals that shut off neurons in the spinal cord, causing temporary paralysis of the limb muscles.
If something interferes with this paralysis, people will begin to physically ’act out’ their dreams—a rare, dangerous problem called REM sleep behavior disorder.
REM sleep stimulates the brain regions used in learning. This may be important for normal brain development during infancy, which would explain why infants spend much more time in REM sleep than adults.
Like deep sleep, REM sleep is associated with an increased production of proteins. One study found that REM sleep affects the learning of certain mental skills. People taught a skill and then deprived of non-REM sleep could recall what they had learned after sleeping, whilst people deprived of REM sleep could not.
Some scientists believe dreams are the cortex’s attempt to find meaning in the random signals that it receives during REM sleep. The cortex is the part of the brain that interprets and organizes information from the environment during consciousness. It may be that, given random signals from the pons during REM sleep, the cortex tries to interpret these signals as well, creating a ’story’ out of fragmented brain activity....
