What Do We Mean by Imagination?
When you hear the word imagination, what comes to mind? Most likely, it is creativity, fiction, or fantasy—the invention of things that do not exist.
Many are familiar with visualization as one aspect of imagination. We encounter it in guided meditations or in the way athletes mentally rehearse a movement before performing it. The common association is that imagination is something we intentionally create—as if it were a talent you either have or you don’t.
But what if imagination is broader than this? What if we understood it as a constant, active process—the inner field where our thoughts, mental activity, and emotional states take shape and unfold within us? What if imagination is not something we occasionally use, but the very function through which the mind operates?
What if imagination colors our reality through constant interpretation—the very moment we drift from direct experience into our interpretation of what is happening? Would this perspective not offer life greater agency? As though it carries a quiet promise—that this field is something we can learn to navigate, instead of just being swept along by it
What If Imagination Is the Core Structure of Experience?
Consider a contemporary formulation by neuroscientist Anil Seth:
“We are all hallucinating all the time; when we agree about our hallucinations, we call it reality.”
The claim reflects predictive processing theory — the idea that perception is an active process in which the brain continuously generates predictions about what is out there and updates them based on sensory input. What we experience as reality is the result of this ongoing negotiation between prediction and incoming signals.
From this perspective, imagination is not only fantasy, visualization, creativity, and fiction. It is also the interpretive engine through which reality is continuously anticipated, rehearsed, and understood.
It is the capacity that allows us to escape the world — and the system through which we construct and interpret it. It is a multisensory simulation faculty, capable of reactivating neural patterns associated with sight, smell, sound, shape, color, and the sensory layers of emotion — even in the absence of external input.
This might sound like too much. But without imagination – how else could a fantasy or a daydream be so rich in detail, color, and feeling?
Key Distinction
“Normal” Perception is a controlled hallucination where the brain’s internal predictions are held in check by sensory data from the outside world. Imagination occurs when those same internal predictions run free, without the “anchor” of external input. Both are made of the same neural fabric.
That Means Your Anxiety Is Imaginal
What if catastrophic thinking, self-criticism, flashbacks, and even obsessive intrusive thoughts are forms of internally generated imagination operating without immediate sensory input?
Not “fantasy” in the literary sense — but the brain’s default strategy for navigating uncertainty.
Mind-wandering research suggests that a large portion of waking cognition occurs in internally generated states associated with the Default Mode Network. These states often involve rehearsal, projection, reconstruction, and counterfactual modeling.
We do not occasionally imagine. We live within ongoing simulation.
This article traces how the concept of imagination has shifted historically — from philosophical faculty to poetic inspiration to modern cognitive construct — and examines what happens when we reclaim its broader structural meaning.
Imagination from a Cognitive Science Perspective
From cognitive science, imagination is often described as a form of mental simulation. This means that the mind has the capacity to generate internal models of reality—without direct sensory input from the external world. Rather than merely inventing fiction, the brain continuously constructs simulations of:
-
possible futures
-
remembered past events
-
social interactions
-
interpretations of the present moment
Research suggests that this capacity is closely tied to how the brain predicts, interprets, and navigates reality (Barsalou, 2008; Buckner & Carroll, 2007). In this sense, imagination is not an occasional creative act. It is a fundamental function of how the mind operates.
Imagination — A Companion of Consciousness
Seen from this perspective, imagination is not merely a creative faculty but an ever-present companion of consciousness. It participates in how experience is shaped from within — through fleeting thoughts, intrusive images, emotional scenarios, bodily anticipations, and symbolic representations.
Imagination delivers experience in the form of impressions: thoughts, feelings, atmospheres. Emotion and imagination move reciprocally, each influencing the other. Philosophically, this aligns with accounts that describe imagination not as decoration, but as a structural feature of lived experience (Sartre, The Imaginary).
A simple example makes this tangible. Imagining biting into a lemon can trigger salivation and muscular tension, as though the fruit were present. The body responds to simulation. Likewise, emotions often become conscious through imaginative form — a heaviness in the chest, a tightening in the stomach, a sense of pressure or darkness.
Even repetitive or dysfunctional thought patterns can be understood in this light: as simulations in which emotion and cognition intertwine into the stream we experience as our life.
We may meet these inner movements or push them aside. What is avoided rarely disappears; it often continues to operate in the background. When we pause and attend more carefully, imagination can become not only the medium of our entanglement, but also the means through which understanding and change become possible.
Key Distinction
Imagination is not opposed to reality. It is the process through which reality becomes experience. Thought, emotion, image, and bodily response move together.
Imagination and Its Meanings – A Historical Perspective
In English, the word imagination carries a persistent ambivalence. It can denote creativity, vision, and inventive capacity. Yet it is just as often used dismissively — “it’s just your imagination” — implying unreality, exaggeration, or error. This dual usage reflects an unresolved tension within the term itself.
Comparable patterns appear in other Germanic languages. In German, Phantasie may signal artistic creativity, but it can also suggest unreliability or detachment from reality. In contrast, Romance languages such as French (imagination), Spanish (imaginación), and Italian (immaginazione) are more commonly used to refer to the mind’s capacity to generate inner representations without as strongly implying falseness. In these contexts, the word may describe remembering, anticipating, rehearsing, or inventing with relative neutrality.
Such differences are subtle, yet they shape cultural attitudes toward inner experience (Taylor, 1989). In some linguistic traditions, imagination is celebrated as a source of creativity and insight. In others, it is treated with suspicion, as something that must be corrected or restrained.
Despite these variations, the underlying faculty remains constant: the capacity to form representations not directly determined by present sensory input.
In this text, imagination is not positioned in opposition to reality. Rather, it designates the ongoing process through which images, sensations, affects, and meanings take form within lived experience. Whether adaptive or distorted, voluntary or spontaneous, these internal constructions participate in how reality is interpreted and inhabited.
Understood in this broader sense, imagination is not a special talent. It is a structural feature of consciousness.
From Phantasia to Imagination – The Beginning of the Word
The conceptual lineage of imagination can be traced to Aristotle’s notion of phantasia in De Anima (Aristotle, trans. 1984). He described it as a vital bridge between raw perception (aisthesis) and conscious thought (nous). Crucially, Aristotle did not limit this faculty to vision. Phantasia was understood as multisensory, linking perception across the senses to memory, movement, desire, and emotion.
This broad understanding carried into the Roman and medieval world under the Latin term imaginatio. Thinkers such as Thomas Aquinas described imagination as a mediating faculty between sense and intellect (Aquinas, Summa Theologica). It was not conceived as detached fantasy, but as an embodied process — the mechanism through which lived sensory experience becomes organized and made available for thought and action.
Over time, the concept gradually narrowed, increasingly associated with visual imagery or creative invention. By returning to phantasia, we recover a more structurally expansive meaning.
In De Anima, Aristotle characterizes phantasia as a faculty that:
-
Arises from perception
-
Preserves perceptual forms
-
Makes them available even when the external object is no longer present
-
Functions as an intermediary between perception and thinking
Although visual examples were frequently used, phantasia was inherently connected to:
-
All the senses
-
Memory
-
Movement
-
Desire (orexis)
-
Emotion
Imagination was therefore not originally conceived as a detached faculty of fantasy, but as an embodied process shaping how sensory experience becomes thought and how perception guides action. Long before modern neuroscience described predictive models and internal simulation, this faculty was already understood as central to how humans think, feel, and move.
Key Distinction
Phantasia (Ancient) was a multisensory bridge linking emotion, movement, and memory. Modern Fantasy is often narrowed down to mean just “seeing pictures.” Reclaiming the ancient meaning allows us to work with the entire body—tone, temperature, and tension—not just the eyes.
Where Does Imagination Arise?
Classical psychology has often described imagination in layered terms: the unconscious, the subconscious (or preconscious), and the conscious. These are not precise anatomical locations in the brain. Rather, they are ways of describing different modes through which inner experience takes shape.
Contemporary neuroscience does not locate imagination in a single “center.” Instead, it shows that imagination emerges from interacting brain networks that integrate emotion, memory, bodily signals, and reflective thought.
The Unconscious
The unconscious refers to processes that operate outside awareness yet influence how we feel and respond.
Neuroscience associates rapid, automatic emotional processing with subcortical and limbic structures, including the amygdala and hippocampus (LeDoux, 1996). These systems register emotional significance and link it to memory — often before we consciously recognize what is happening.
In this sense, unconscious imagination may appear as sudden images, symbolic impressions, bodily reactions, or emotional shifts that seem to arise “on their own.” The body tightens. A mood changes. A scene flashes inwardly.
Importantly, the unconscious is not reducible to a single structure. It reflects distributed processes that operate prior to deliberate awareness.
The Subconscious / Preconscious
The subconscious describes material that is not fully conscious but can become so with minimal attention — vague feelings, drifting images, anticipations, or inner dialogues.
Neuroimaging research has linked such internally generated activity to the Default Mode Network (DMN) (Raichle et al., 2001; Buckner & Carroll, 2007). This distributed network becomes active when the mind turns inward — during remembering, imagining the future, reflecting on oneself, or mind-wandering.
Here, imagination takes the form of ongoing inner simulation: narrative fragments, atmospheres, rehearsed conversations, quiet anticipations. Much of this unfolds automatically, yet it remains accessible to awareness.
The Conscious
Conscious imagination involves deliberate attention and intentional shaping. When we visualize intentionally, reflect on our reactions, or reshape an inner image, we engage regulatory systems in the prefrontal cortex associated with attention and cognitive control.
In this mode, imagination is not only something that happens to us — it becomes something we can work with.
An Integrated View
While the language of “unconscious” and “conscious” remains theoretical, neuroscience supports a functional distinction between:
-
rapid emotional processing
-
internally generated self-reflection
-
deliberate regulation and attention
Imagination can therefore be understood as a layered, dynamic process spanning body, emotion, memory, and reflective awareness.
Rather than belonging to one part of the brain, it arises from their interaction.
How Does Imagination Manifest?
Imagination does not appear in a single sensory form. It may unfold as inner language, mental imagery, bodily sensation, or diffuse emotional atmosphere. Some experiences are vivid and scene-like; others are subtle, fragmentary, or barely noticeable.
Inner Language
Much of imagination takes linguistic form. The inner voice — commentary, rehearsal, reflection, self-questioning — often operates continuously in the background of awareness. Some of this activity is deliberate and structured. Much of it unfolds automatically.
When inner language links with memory, imagery, or bodily sensation, it can intensify emotional states and shape how we perceive a situation. A single internal sentence — repeated or charged with meaning — may influence mood, expectation, and behavior.
Sensory and Embodied Imagery
Imagination may also emerge as sensory representation: images, sounds, smells, tactile impressions, or interoceptive sensations such as tightness, warmth, or pressure. These experiences can arise without external stimulation.
Neurocognitive research suggests that mental imagery recruits neural systems that overlap with perception (Nanay, 2023). This helps explain why imagined scenes can evoke genuine physiological responses — accelerated heartbeat, muscular tension, salivation, or emotional shifts.
Importantly, not all imagination is pictorial. It may appear as felt anticipation, bodily readiness, or atmosphere — a pre-verbal shaping of experience that precedes explicit thought.
Closing the Circle: The Consciousness From Ancient Times to Modern Science
When we view human consciousness through the lens of both modern neuropsychology and ancient tradition, a striking alignment emerges. What modern science describes as the interplay between the Limbic System (responsible for emotional reactivity and survival instincts), the Default Mode Network (responsible for internal simulation and mental time travel), and the Prefrontal Cortex (responsible for directed attention and executive control), was articulated in indigenous cultures as a practical map for human change.
Perhaps we are not “inventing” new psychological truths, but rather rediscovering the mechanisms that ancestral traditions mastered through ritual and introspection. Transformation, in this light, is not an intellectual exercise; it is the synchronization of three distinct forces of consciousness:
1. The Embodied Base (Hugr / Ku)
This is the instinctive, memory-laden layer of the psyche. In the Old Norse tradition, Hugr represented the “soul” or “mind” that resides within the body, carrying intentions and deep-seated emotions (Price, 2019). Similarly, in the Hawaiian Huna tradition, Ku is the subconscious, bodily-based aspect of the self that stores memories and drives instinctual reactions (Long, 1948).
In modern terms, this is bottom-up processing: the raw data of trauma and impulse arising from the body and the Limbic System long before the rational mind intervenes (LeDoux, 1996).
2. Directed Activation (Óðr / Mana)
This is the “fuel”—the emotional charge and focused intention. In Norse mythology, Óðr is the inspired energy that puts the mind in motion (MacKenzie, 2014). In Polynesian cultures, Mana is the spiritual power concentrated through intention. It acts as the bridge; without this energy—the physiological arousal and activation of our nervous system—our goals remain dry concepts.
3. Imaginal Structuring (Draumr / Inner Vision)
This is the space where reality is modeled. Draumr (Old Norse for “dream” or “vision”) refers to the structured inner space where reality is perceived beyond the physical (Price, 2019). This is top-down processing: using the conscious Prefrontal Cortex to intentionally reorganize internal material and guide the simulations of the Default Mode Network (Pearson et al., 2015).
The Convergence of Change
True change occurs when these forces align. What we now call “neuroplasticity” or “cognitive shifting,” these earlier traditions described as the alignment of soul-parts.
By using directed intention (Óðr/Mana) to meet the instinctive impulses of the body (Hugr/Ku) within the space of the imagination (Draumr), we engage the entire system. We move from reacting to automatic patterns to actively participating in our own experience.
In this light, imagination is not a flight from reality. It is a functional bridge between the body and the mind—a way to reorganize the internal structures that shape how we feel and act in the world. As we look at these layered models of the self, we find that ancient maps and modern science are often pointing toward the same territory.
Transition: From Understanding to Practice
The realization that consciousness is composed of these interacting forces—embodied memory (Hugr), focused energy (Óðr), and inner vision (Draumr)—is not just a philosophical insight. It is a practical tool.
When we engage in imaginative work, we are essentially performing a “soul-alignment.” We are using our directed focus (Óðr) to enter the imaginal field (Draumr) and offer a new experience to our instinctive, bodily self (Hugr/Ku). Transformation occurs not when we think differently, but when we feel differently because our inner imagery has shifted.
The following exercises are designed to help you move from being a passive observer of your imagination to an active participant in your own inner landscape.
Key Distinction
If imagination shapes experience, then working with imagination means working with the structure of emotion itself. Change begins where inner simulation shifts.
How to Work with Imagination – A Simple Guide
Imagination is already active.
The question is not how to create it, but how to work with it.
These are examples of how to use imagination if you ever get stuck in a loop of anxiety, anger, or self-criticism. When that happens, stop for a while. This is your imagination at play. Feel into it; take a look at it. Notice:
An image. A tone. A subtle scene running just beneath your thoughts.
Instead of arguing with it or pushing it away, you can enter it consciously and make small adjustments.
Below are three ways to begin.
1. The Weight of the Future (Anticipatory Stress)
You may notice a tightening when thinking about an upcoming task or a demanding period.
Pause: What am I seeing inside right now?
Perhaps it is a specific room or a vague sense of gray pressure. Instead of turning away, stay with the image.
Ask: What does this situation need?
The answer might be a word (calm), a sensation (steadiness), or a symbol (light). Let that new element enter the scene. Stay with it until your breathing slows.
2. Lingering Anger
Sometimes a conflict continues long after it is over. The scene replays. The body tightens as if it is happening again.
Freeze the inner image for a moment. See both people clearly.
Now increase the distance between you just a little. Notice your posture inside the image. Let it become upright and grounded.
Observe what happens in your body. Often the heat shifts. The pressure softens.
Your body responds to imagined scenes as if they are real. When the image changes, the response changes.
3. Self-Criticism
A harsh inner voice may appear suddenly. Sharp. Close. Familiar. Instead of arguing with it, locate it.
Where is it coming from?
Is it above you? Behind you? Very near?
Now lower its volume slightly. Move it further away.
Or imagine a steady, calm version of yourself standing beside you — not fighting the voice, simply present.
Stay with the adjustment until something in your body softens.
What Matters Most
Imaginative work is complete when the body shifts.
Breathing slows. The chest loosens. There is a little more space inside.
You are working directly with the inner simulation that shapes how emotions arise.
Moving Into Integration
The exercises above are small points of entry into a vast internal landscape. By practicing these subtle shifts, you are training your brain to recognize that its “simulations” are not fixed truths—they are fluid structures that can be reshaped.
As you move back into your day, notice how your imagination continues to operate in the background. Each time you consciously adjust an inner tone or image, you are practicing the ancient art of “soul-alignment” within a modern neurobiological framework. You are no longer just a passenger in your mind; you are learning the language of the engine itself.
