Understanding Dreams
Every night, your brain tells you stories. Sometimes wonderful, sometimes unsettling, always fascinating. Dreams have accompanied humanity since the dawn of time, and yet they retain a measure of mystery that neither science nor philosophy has fully unraveled. Understanding why you dream is already a first step toward knowing yourself better.
Why Do We Dream?
While you sleep, your brain doesn’t really rest — it works. It is during the REM (Rapid Eye Movement) phase of sleep that most dreams occur. During this phase, your brain activity is almost as intense as when you’re awake, while your muscles are temporarily paralyzed to prevent you from physically “living out” your dreams.
Neuroscience has identified several essential functions of dreaming. The first is memory consolidation: during the night, your brain sorts through the day’s information, strengthens important memories, and discards the superfluous. This is why you often dream about recent events — your mind is literally “filing its records.”
The second major function is emotional regulation. Studies conducted by neuroscientist Matthew Walker have shown that REM sleep acts as a natural overnight therapy. Your brain replays emotionally charged experiences in a chemically different environment — with reduced noradrenaline levels — which allows it to “deactivate” the emotional charge associated with the memory. In other words, dreaming helps you digest your emotions.
Finally, dreaming promotes creativity and problem-solving. Freed from the logical constraints of waking life, your brain establishes unexpected connections between seemingly unrelated ideas. This is why some solutions emerge “upon waking” — they were worked out during the night.
The Great Theories of Dreams
Over the centuries, many thinkers have tried to unlock the mystery of dreams. Three major figures have particularly shaped our understanding.
Sigmund Freud: The Fulfillment of Unconscious Desires
For Freud, the dream is the "royal road to the unconscious." In his foundational work The Interpretation of Dreams (1900), he argues that every dream is a disguised fulfillment of a repressed wish. The manifest content of the dream — what you remember — is merely a façade. Behind it lies latent content, made up of drives and desires that your conscious mind refuses to accept. The "dream work" transforms these desires into acceptable symbolic images. Thus, dreaming of flying might express a desire for freedom or power, and dreaming of water might relate to deep emotions connected to birth or sexuality.
Carl Gustav Jung: Individuation and Archetypes
Jung, a former disciple of Freud, developed a different vision. For him, the dream is not a disguise but a direct message from the unconscious that seeks to restore psychic balance. Dreams draw from the collective unconscious — a reservoir of universal images shared by all of humanity, the famous archetypes. The Shadow, the Anima, the Animus, the Wise Old Man: these figures appear in dreams to guide the process of individuation — that is, the path toward self-realization. According to Jung, listening to your dreams means listening to the deep wisdom of your soul.
Fritz Perls: The Dream as Self-Integration
The founder of Gestalt therapy proposes a radically different approach: every element of the dream — character, object, place — is a part of yourself. Dreaming of an aggressive dog does not refer to a universal symbol, but to a facet of your own personality that you have not yet integrated. Perls’ method consists of “becoming” each element of the dream, giving it a voice, and dialoguing with it. This experiential approach allows you to reintegrate fragmented parts of the self and regain a sense of inner unity.
Dreams and Emotions
If you’ve ever been woken by a nightmare with your heart pounding, you know how real emotions in dreams can be. This is no coincidence: the brain regions responsible for emotions — the amygdala and the prefrontal cortex — are particularly active during REM sleep.
Research shows that the most frequent emotions in dreams are fear, anxiety, and surprise. Positive emotions exist too, but they often leave fewer traces in memory upon waking. This negative bias has an evolutionary function: dreaming prepares you for potential threats by simulating dangerous situations in a safe environment.
Recurring dreams deserve special attention. When the same theme returns night after night — being chased, arriving late, losing your teeth — it is generally a sign of an unresolved emotion or a persistent inner conflict. The dream repeats its message until you’ve heard it. Taking the time to analyze a recurring dream is often the best way to make it disappear.
The emotions felt in a dream are often more revealing than the images themselves. Rather than asking yourself “what does this symbol mean?”, try first asking “what did I feel?” The answer will guide you toward a more accurate and more personal interpretation.
Can You Control Your Dreams?
Yes, and it has a name: lucid dreaming. A lucid dream is a dream in which you become aware that you are dreaming, while continuing to dream. This awareness opens a fascinating door: you can then influence the course of the dream, choose your actions, and explore your dream world in complete freedom.
The phenomenon has been scientifically documented since the work of Stephen LaBerge at Stanford University in the 1980s. Using electroencephalography, he proved that lucid dreamers are capable of sending predetermined eye signals from within the dream, thereby confirming that they are conscious while sleeping.
Several techniques can help foster dream lucidity. The best known is the “reality test”: make a habit, several times a day, of asking yourself “am I dreaming?” and checking by looking at your hands or rereading a piece of text. This habit eventually reproduces itself in the dream, and when your hands distort or the text changes, you realize you’re dreaming.
Lucid dreaming is not just entertainment. It is used in therapy to treat recurring nightmares — the dreamer learns to face their fears in a safe space — and as a personal development tool. It is a unique way to dialogue directly with your unconscious.
