When You Think About Tomorrow

Think about tomorrow — your morning routine, your workday, a meeting, a conversation, or somewhere you expect to be.

Pause for a moment and notice what happens first inside you. Does an image form of a room, a face, or a sequence of events? Or do you first notice something in the body — a tightening, a lightness, a readiness?

Perhaps words begin rehearsing themselves quietly, or a mood appears such as calm, pressure, or anticipation. Is there simply a sense of leaning forward into something not yet here? Stay with it for a few seconds. What is the texture of tomorrow inside you?

When You Think About Yesterday

Now think about yesterday — something specific, like a conversation, a task, or a moment in the afternoon. Notice carefully: do you replay it visually, like a short scene, or do you simply “know” what happened without seeing it clearly?

Does a bodily feeling return before any image becomes sharp? Does a tone come back — embarrassment, relief, irritation, or warmth? Is there a shift in posture or breathing as you recall it?

Whatever you noticed — image, sensation, words, mood, or simple knowing — is imagination in activity. It is already present in the way yesterday returns and in the way tomorrow approaches.

The Language of Visualization

In many contexts — especially in personal development, performance psychology, and meditation — the word “visualize” is used as a general instruction. We are told to visualize success, visualize calm, or visualize the future we want. Often, the instruction functions as an invitation to imagine — to engage with an experience internally.

Yet people respond to this invitation in different ways. Some individuals form clear inner images, others notice bodily sensations, some hear inner dialogue, and some experience a shift in mood or orientation without any visual component at all. There is variation in how inner experience presents itself; this variation is common and does not indicate a deficit. The capacity for imagination does not depend solely on inner vision. The channels through which experience organizes internally are multiple.

The Power of Somatic Knowing

For many, the most direct channel of imagination is not the eyes, but the “felt sense.” This is a pre-verbal knowing — a shift in the gut, a change in temperature, or a subtle expansion in the chest. When your body reacts to a memory before you can even remember the details, your somatic imagination is at work. It is a profound intelligence that speaks in the language of biology, bypassing the need for a clear mental “movie.”

Visualization as Internal Representation in Imagination

From a psychological and neurocognitive perspective, the brain is constantly organizing experience. It does not simply register the world as it is. Instead, it interprets, anticipates, and shapes what we perceive.

Research in predictive processing and embodied cognition suggests that perception involves an ongoing integration of sensory input, memory, emotional tone, and expectation (Clark, 2016). What we experience is therefore not a direct copy of reality, but a constructed interpretation formed within the nervous system. This constructive process is active not only when we perceive the present, but also when we imagine. Visualization reflects one way this internal modeling becomes consciously accessible — as mental imagery.

This internal modeling is experienced subjectively through multiple channels:

Bodily sensations (interoception) — The felt sense of the body’s internal state, such as a tightening in the chest, warmth in the stomach, or a shift in breathing. This is the body’s way of participating in imagination (Craig, 2009).

Emotional tone — The mood or feeling that colors inner experience — calm, pressure, excitement, dread. Emotions are not separate from imagination; they are part of its texture (Damasio, 1994).

Inner speech and narrative — The quiet voice that comments, rehearses, or tells a story. This is the verbal dimension of imagination (Alderson-Day & Fernyhough, 2015).

Auditory imagery — Hearing sounds, voices, or music in the mind’s ear. This is the auditory counterpart to visual imagery.

Motor impulses and simulation — The sense of movement, readiness, or action that accompanies imagination. Even when we are still, the motor cortex can activate as if we were moving (Jeannerod, 2001).

Spatial orientation — A sense of direction, location, or arrangement. This is the spatial map of inner experience.

Visual imagery — The mental pictures that some people experience. While often emphasized, this is only one channel among many.

The Nervous System and Imagination

Understanding the brain regions involved in imagination helps explain why it is so powerful and why it can affect the body so deeply. Here is a guide to the key brain regions and what they do.

The Visual Cortex — The Brain’s “Seeing” Center

Location: At the back of the brain, in the occipital lobe.

What it does: The visual cortex processes everything we see — shapes, colors, movement, and faces. When you look at something, this region becomes active. What is remarkable is that it also becomes active when you simply imagine something (Kosslyn et al., 2001). This is why visual imagery can feel so real — the brain’s “seeing” regions are engaged even when the eyes are closed. For some people, the visual cortex activates strongly during imagination. For others, it is less active. This variation is normal and does not mean imagination is absent.

Why this matters: The same neural pathways are used whether we perceive something or imagine it. This is why vivid imagination can feel so real — and why it can affect the body as if the imagined event were actually happening.

The Somatosensory Cortex — The Brain’s “Feeling” Center

Location: On the top of the brain, in the parietal lobe.

What it does: The somatosensory cortex processes touch, pressure, temperature, and pain from all over the body. When you feel a physical sensation — a warm hand on your arm, a tightness in your chest — this region becomes active. During imagination, the somatosensory cortex can also become active (Kosslyn et al., 2001). This is why a remembered embrace can feel almost real, or why imagining a stressful situation can create a physical sense of tension. The brain processes the felt sense of the imagined body in much the same way as it processes real body sensations.

Why this matters: Because the somatosensory cortex activates during imagination, inner experience is not “just in the head.” It is felt in the body.

The Insula — The Brain’s “Inner Body” Monitor

Location: Deep inside the brain, folded within the temporal and frontal lobes.

What it does: The insula is the brain’s center for interoception — the perception of the body’s internal state (Craig, 2009). It monitors heartbeat, breathing, gut activity, and other internal signals. The insula provides the “felt sense” of the body from moment to moment. When you notice a shift in your gut, a change in your breathing, or a sense of expansion or contraction in your chest, the insula is active. This region is also active during imagination, especially when the imagined experience carries emotional weight (Damasio, 1994).

Why this matters: The insula is central to the experience of felt sense. It is the brain region that translates bodily signals into the conscious experience of feeling.

The Limbic System — The Brain’s “Emotional” Center

Location: A network of structures deep within the brain, including the amygdala and hippocampus.

What it does: The limbic system is the brain’s emotional center (LeDoux, 2000). It evaluates whether an experience is important, threatening, rewarding, or safe. The two most relevant structures are:

• The amygdala — A small, almond-shaped structure located deep in the temporal lobes, just in front of the hippocampus. It processes emotional significance and is especially involved in fear and threat responses. When you imagine a frightening scenario, the amygdala becomes active, triggering the body’s stress response (LeDoux, 2000).

• The hippocampus — A seahorse-shaped structure located next to the amygdala. It is essential for memory formation and retrieval. The hippocampus is also involved in imagination because it retrieves and recombines memories to construct new imagined scenes (Schacter et al., 2007). A 2025 study published in Nature demonstrated that the human hippocampus can voluntarily generate new, imagined trajectories during sleep, constructing novel paths that had never been experienced (Nature, 2025).

Why this matters: The limbic system is why imagination carries emotional force. An imagined threat can trigger the same fear response as a real one because the amygdala does not distinguish clearly between perception and imagination.

The Motor Cortex — The Brain’s “Action” Center

Location: At the top of the brain, in the frontal lobe.

What it does: The motor cortex initiates and coordinates voluntary movements. When you move your arm or speak, this region is active. When you imagine a movement — such as rehearsing a sports action or picturing yourself reaching for something — the motor cortex also becomes active (Jeannerod, 2001). Imagining an action activates the same neural pathways as actually doing it.

Why this matters: This is why mental rehearsal works. The brain does not distinguish clearly between imagined action and actual action. The motor cortex activates in both cases, which is why athletes and performers use imagery to improve their skills.

The Nervous System and Inner Experience

The experiences that appear in the mind are not independent of the body’s physiological state. The nervous system continuously shapes the emotional tone, intensity, and content of inner experience.

How Nervous System State Shapes Inner Experience

When the nervous system is in a state of high arousal (the “fight or flight” response), inner experience tends to become vivid, urgent, and difficult to disengage from. It is often threat-biased and repetitive, with worst-case scenarios playing out in the mind. This state is associated with activation of the sympathetic nervous system, which prepares the body for action (Porges, 2011).

When the nervous system is in a state of safety and rest (the “rest and digest” response), inner experience tends to become slower, more exploratory, and more creative. Symbolic, associative, and flexible thinking becomes possible. This state is associated with activation of the parasympathetic nervous system, which supports rest and recovery (Porges, 2011).

Why this matters: The same inner content can feel completely different depending on whether we are stressed or at ease. A worrying thought can feel overwhelming when the nervous system is activated. That same thought can be observed with curiosity and openness when the nervous system is settled. This is why regulation of the nervous system is often a prerequisite for deep inner work.

The Autonomic Filter

The autonomic nervous system acts as a filter for imagination. When we are stressed, the filter narrows — inner experience becomes more repetitive, rigid, and threat-focused. When we are safe, the filter opens — inner experience becomes more flexible, creative, and expansive (Porges, 2011; Ogden et al., 2006).

This is why trauma-informed therapeutic approaches prioritize the nervous system when working with inner experience. Rather than engaging with inner content purely through intellectual interpretation, these methods use somatic tracking — monitoring breathing, muscle tension, and heart rate while the experience is present (Levine, 1997). When the nervous system begins to settle through regulation, the associated inner experience often changes spontaneously. Scenes become less rigid, new perspectives appear, and the emotional “charge” softens.

Two Directions of Imagination

Sometimes imagination is intentional — you deliberately picture a future conversation, rehearse a scene, or try to create an image. This is often called top-down imagination because it originates in the higher brain regions involved in conscious control, particularly the prefrontal cortex (the brain’s “executive center” located behind the forehead).

At other times, imagination arises on its own — a tightness in the stomach when you think of tomorrow, a sudden warmth when you remember yesterday, a shift in tone before any picture forms. This is often called bottom-up imagination because it originates in the body and travels upward through the nervous system.

These movements can be understood as different directions of organization — from deliberate shaping downward, or from bodily and emotional signals upward. Both participate in how experience becomes structured internally.

The Everyday Process – Imagination in Motion

When you notice how tomorrow forms within you, or how yesterday returns, you are observing imagination in motion. It is the ongoing shaping of experience itself.

If imagination is not limited to visualization or a special state, but is something ongoing, then everyone is already working with it — whether they know it or not.

If imagination organizes experience continuously, then learning how to regulate and work with it becomes central. The first step is understanding how imagination interacts with the nervous system.

Key insight: Imagination is not a special state we occasionally enter. It is the ongoing process through which all inner experience takes shape — through sensation, emotion, words, orientation, and sometimes images. The task is not to learn to visualize. The task is to recognize the imagination that is already happening.

Visualization as Internal Representation in Imagination

From a psychological and neurocognitive perspective, the brain is constantly organizing experience. It does not simply register the world as it is. Instead, it interprets, anticipates, and shapes what we perceive.

Research in predictive processing and embodied cognition suggests that perception involves an ongoing integration of sensory input, memory, emotional tone, and expectation (Clark, 2016; Barrett, 2017). What we experience is therefore not a direct copy of reality, but a constructed interpretation formed within the nervous system. This constructive process is active not only when we perceive the present, but also when we imagine. Visualization reflects one way this internal modeling becomes consciously accessible — as mental imagery.

This internal modeling is experienced subjectively as:

• bodily sensations (interoception)

• emotional tone

• inner speech and narrative

• auditory imagery

• motor impulses and simulation

• spatial orientation

• visual imagery

Imagination is therefore the experiential material through which life is lived internally. It is not separate from perception. It is how perception becomes meaningful.
