Dreaming is an intimate experience. It’s something that happens behind closed doors, when the world falls silent. And yet, dreaming is anything but random: while the body rests, the brain continues to sort, make connections, and feel. It works differently. So, why do we dream? What do our nighttime dreams tell us, and how can we make sense of their meaning without forcing an interpretation? Here, we’ll take a calm approach: a few points of reference, some nuance, and the freedom not to explain everything.

Dreams and Sleep
What is a dream?
A dream is a mental experience that occurs during sleep. It can take the form of a scene, a series of images, a vague thought, or a sensation. Sometimes the emotion is clear; other times, only a general atmosphere remains. And one simple point of reference helps put things into perspective: a dream isn’t necessarily a message to be deciphered. It is, first and foremost, an activity of the sleeping brain.
What makes dreams so baffling is the way they come together. The brain draws on recent memories, long-forgotten emotions, and hidden concerns. It mixes, condenses, and transforms them. And it is often this strangeness that makes us want to search for the meaning behind our dreams, as if something were speaking from behind the scenes.
Sleep Stages and Their Impact on Dreams
To understand why we dream, we need to view the night as a rhythm. Sleep progresses in cycles: lighter stages, deeper stages, and a distinct stage known as rapid eye movement (REM) sleep. It is often during this stage that dreams become most vivid, accompanied by high levels of brain activity and rapid eye movements. The NINDS notes, in particular, that REM sleep begins about 90 minutes after falling asleep and then recurs regularly throughout the night.
But we don’t just dream during REM sleep. We can also dream during non-REM sleep: these dreams are shorter and more like a thought than a story. To get a better understanding of how our nights unfold, you can revisit “The Sleep Cycle: How Do Our Nights Unfold?” or our guide to the four stages of sleep.
Why do we dream?
Theories About the Function of Dreams
There is no single explanation, but several theories. Some describe dreaming as a process of integration: the brain consolidates what it has learned, reactivates memories, and creates new associations. Others emphasize an emotional function: dreaming is said to help process experiences, “process” emotions, and give shape to what was previously unclear.
Research in neuroscience on the link between dreams, memory, and emotions supports this view, albeit with caution. A review of the functional role of dreaming in emotional processes suggests, for example, that sleep—and REM sleep in particular—plays a role in emotional regulation by modulating the emotional intensity of memories.
Finally, a more “evolutionary” hypothesis views dreams as a simulation: a risk-free form of training. We do not “predict” the future, but rather explore scenarios, test our reactions, and overcome our fears. Science often advances in layers, and dreams retain their share of mystery—which does not prevent us from observing them with gentleness.
Do we dream every night?
In the vast majority of cases, yes: we dream almost every night, but we don’t always remember them. Recall depends on micro-awakenings, the moment we emerge from sleep (often at the end of a cycle, when REM sleep lengthens), and also on a very simple factor: the attention we pay to our dreams. Paradoxically, a night filled with awakenings can actually improve recall…
Do dreams have any meaning?
The meaning of dreams is a sensitive subject because it touches on something deeply personal. What we can say without overstepping the bounds of science is this: dreams often have an emotional meaning rather than a literal one. They depict themes, tensions, desires, and fears, but in a transformed way. A dream is not a universal code: the same symbol does not mean the same thing from one person to another.
That is why the most accurate approach is often the simplest: observe, take notes, and connect the dream to its context, without trying to impose an interpretation. Our guide, *Understanding Your Dreams*, offers guidelines for interpreting a dream as a possible mirror—never as an imposed truth.
Lucid Dreaming
Definition and Characteristics of Lucid Dreaming
A lucid dream is a dream in which one becomes aware that one is dreaming. This lucidity can be brief, or, conversely, sustained, with a very clear sense of presence. Some people are also able to influence the dream’s plot: changing the setting, calming a tense situation, or exploring a question. Lucid dreaming is often associated with rapid eye movement (REM) sleep, although the boundaries between states of consciousness are sometimes more subtle than one might imagine.
How do you induce a lucid dream?
Induction methods do exist, but they are not neutral: some rely on setting an alarm for the end of the night, while others involve intention exercises (repeating a phrase to oneself before falling back asleep). A common caution is often raised: certain techniques can fragment sleep, especially if practiced intensively. A review article in *Frontiers in Psychology* discusses precisely this point: cultivating lucidity should not come at the expense of rest.
At Kipli, we stick to a simple rule of thumb: if a practice makes the night less restful, it misses the point. Sleep isn’t a performance—it’s a foundation.
The Benefits of Lucid Dreaming
The potential benefits are often cited in connection with creativity, exploration, and sometimes anxiety management. Some approaches also focus on using lucid dreaming to address nightmares, but these are topics that require a nuanced approach: what helps one person may agitate another.
Nightmares and Their Meanings
What causes nightmares?
Nightmares are distressing dreams, often filled with fear or anxiety, that can cause a sudden awakening. They are frequently associated with rapid eye movement (REM) sleep, although they can also occur at other times. Stress, emotionally charged periods, sleep deprivation, certain medications, or traumatic events can increase their frequency.
How do you deal with nightmares?
When nightmares become recurrent, there are proven approaches. One of the best known isImagery Rehearsal Therapy (IRT), a technique that involves rewriting the nightmare scenario while awake and then mentally rehearsing it. The American Academy of Sleep Medicine recommends IRT for the treatment of nightmare disorder (see the guide via AASM).
And here’s a simple but essential guideline: if a dream triggers intense distress or is part of a traumatic experience, seeking help from a healthcare professional is a protective measure, not a sign of weakness. Sleep disorders can also be treated.
Nightmares During REM Sleep
REM sleep is an intense phase: the brain is active, while the body is “put to rest” in terms of motor function. This contrast can make certain nightmares feel very immersive. Understanding the mechanisms of REM sleep helps alleviate feelings of guilt: a nightmare isn’t a choice—it’s a phenomenon that happens, often when the emotional system is highly activated.
Memories of Her Dreams
Writing down your dreams doesn't have to be a chore. A notebook on your nightstand, a few lines when you wake up—a date, a feeling, an image. Just enough to leave a record. Our guide to remember one's dreams provides simple cues to encourage dream recall without disrupting sleep.
How can you remember your dreams?
Remembering one’s dreams depends less on “memory” in the academic sense than on the circumstances of waking up. A sudden awakening often erases all traces of a dream. A gentler awakening leaves room for fragments to resurface. Dreams fade quickly: they do not unfold like a conventional narrative; they follow their own logic.
You can help your memory by taking a moment at the end of the night—avoiding the urge to immediately check your notifications and staying still for a few seconds. And if nothing comes to mind, it’s not a failure: your brain was dreaming, even if your memory didn’t capture the image.
Techniques for Improving Dream Recall
The simplest technique is often the most effective: write it down right away. Even just one word. Even just a feeling. The brain quickly realizes that we’re giving it importance, and the likelihood of remembering it increases. In the same vein, setting an intention before going to sleep (“tomorrow, I’ll remember”) can serve as a trigger. Again, it’s all about gentleness: we set a reminder, but we don’t demand anything.
The Importance of Remembering Dreams
Remembering your dreams isn’t necessary for “sleeping well.” But it can serve as a tool for self-observation: a way to sense fatigue, a period of stress, or, conversely, a sense of calm. Dreams don’t tell the whole story, but they can sometimes signal an imbalance, much like the weather inside you.
Dreaming isn’t a mystery to be solved, but a phenomenon to be approached. With a little science, a little observation, and the freedom to not understand everything. Kiplism, at its core, often begins there: slowing down, observing, and letting the night do its work.
