The Body Remembers What the Mind Forgets

In the 1970s, a young researcher named Peter Levine had a mystical experience that would shape decades of trauma therapy. He reported engaging in a year-long Socratic dialogue with an apparition of Albert Einstein while developing his doctoral dissertation on stress. Later, a dream convinced him he had been "assigned" to protect ancient knowledge from Celtic Stone Age temples and Tibetan traditions, translating it into scientific Western terms.

This is the origin story of somatic experiencing—a therapy now practiced worldwide, built on the radical premise that trauma lives not in our thoughts but in our bodies.

Whether you find Levine's mystical encounters inspiring or troubling probably says something about how you'll receive the therapy itself. Somatic experiencing sits at an uncomfortable intersection: it draws on legitimate scientific observations about how stress affects the nervous system, yet it emerged from a tradition steeped in theories about "life-force energy" and blocked emotions. It has a growing evidence base, yet that evidence remains "weak" by conventional scientific standards. Practitioners range from licensed psychologists to yoga teachers to clergy members, each operating within vastly different scopes of practice.

To understand somatic experiencing, we need to trace its intellectual ancestry—a journey that takes us through psychoanalysis, breathing exercises in pre-war Germany, and the controversial science of the vagus nerve.

The Grandfather: Wilhelm Reich and Blocked Emotion

Before there was somatic experiencing, there was Wilhelm Reich.

Reich was a psychoanalyst who broke with Freud over a fundamental question: where does trauma actually live? Freud believed psychological problems resided in the mind—in memories, associations, and unconscious conflicts that could be accessed through talking. Reich disagreed. He thought the body held emotion physically, that psychological pain could become literal muscular tension.

Watch someone receiving bad news. Their shoulders might rise. Their jaw might clench. Their breathing might become shallow. Reich observed these patterns and developed a theory: emotion that isn't fully expressed gets "blocked" in the body. These blocks accumulate. They become chronic muscle tension. And they keep the original emotional charge trapped, like a battery that never discharges.

The solution, Reich believed, was to work directly with the body to release these blocks. Various techniques—breathing exercises, physical movement, direct touch—could help discharge the stored emotional energy.

This was heretical in the 1930s and remains controversial today. But Reich's basic insight—that mind and body aren't separate systems but one integrated whole—influenced an entire field. Two of his students, Alexander Lowen and John Pierrakos, went on to develop Bioenergetics, another body-centered therapy. They talked about a natural rhythm in organisms, a pulse between contraction and expansion, like a pendulum swinging.

That pendulum metaphor would reappear in somatic experiencing under a different name.

The Grandmother: Elsa Gindler and Sensory Awareness

While Reich gets much of the credit for body-centered therapy, there's another lineage worth knowing.

Elsa Gindler was a German movement teacher whose work actually preceded Reich's and influenced him. Her approach was gentler, more contemplative. Rather than trying to break through muscular blocks, she taught people to pay attention to their bodies with careful, non-judgmental awareness. What sensations arise when you sit quietly? Where is there tension? Where is there ease?

Gindler's student Charlotte Selver brought this work to the United States, calling it "sensory awareness." She taught thousands of Americans at the Esalen Institute in California—the same hot springs retreat center where the human potential movement was born, where Aldous Huxley lectured and encounter groups met in hot tubs.

Peter Levine was one of Selver's students. From her, he learned what he would later call "fine somatic tracking"—the ability to notice subtle internal sensations with precision and patience.

This is where somatic experiencing differs from Reich's more cathartic approach. Rather than encouraging intense emotional release, SE practitioners guide clients to notice their internal experiences very slowly, very carefully, in small doses.

What Actually Happens in a Session

Imagine you're sitting with a somatic experiencing practitioner. You've come because you were in a car accident six months ago, and you still feel anxious every time you get behind the wheel. Your heart races. Your hands grip the steering wheel too tightly. Sometimes you have flashbacks to the moment of impact.

A cognitive behavioral therapist might help you identify and challenge the thoughts driving your anxiety. "What evidence do you have that you'll get in another accident? What's the statistical probability?" The goal would be to change your thinking, which would change your feelings, which would change your behavior.

A somatic experiencing practitioner takes a different approach. They might ask you to close your eyes and notice what you're feeling in your body right now, just sitting in this safe room. Where is there tension? Where is there relaxation? What happens when you bring your attention to your breathing?

Then—and this is crucial—they would approach the traumatic material very gradually. Not by asking you to vividly imagine the accident, but by asking what happens in your body when you simply think about getting into your car tomorrow. Does your heart rate change? Do you notice any impulse to move—to brace yourself, to turn away, to run?

The theory is that during the accident, your nervous system mobilized for action—to fight or flee—but couldn't complete that action. You were trapped in the car. The energy your body summoned for survival had nowhere to go. And according to SE theory, that energy is still stuck in your system, still trying to complete an action that was interrupted years ago.

The therapy aims to help your body finally complete those defensive movements. The practitioner might notice that when you imagine the accident, your arms tense slightly—perhaps an impulse to brace against the steering wheel. They might invite you to follow that impulse very slowly, letting your arms push outward, feeling the strength in them, noticing what happens in your chest and shoulders as the movement completes.

"Discharge" in SE can look like many things: tears, trembling, warmth spreading through the body, a deep breath, yawning. The idea is that these responses indicate the nervous system returning to baseline after releasing stored stress.

Titration: The Dose Makes the Medicine

Perhaps the most distinctive feature of somatic experiencing is its emphasis on small doses—what practitioners call "titration," borrowing a term from chemistry.

In traditional exposure therapy, the logic runs like this: face your fear directly and repeatedly, and your nervous system will eventually learn that the feared situation isn't actually dangerous. Anxiety will extinguish. The research supporting this approach is extensive. But exposure therapy can be intense, even overwhelming. Some clients drop out because the process feels unbearable.

Somatic experiencing claims to offer a gentler path. Instead of diving into traumatic material, you dip your toe in. You approach the edge of discomfort, notice what happens in your body, then pull back to safety. This back-and-forth movement—approaching distressing material, then returning to calm—has its own name in SE: "pendulation."

The pendulum swings between what practitioners call the "trauma vortex" (the pull toward painful material) and the "healing vortex" (the pull toward resources, safety, and bodily calm). The therapist helps clients weave between these two states, never staying in distress so long that they become overwhelmed.

Is this actually different from graduated exposure therapy? The question is more complicated than it might seem.

Old Wine, New Bottles?

In the 1940s—decades before Peter Levine began developing somatic experiencing—a South African psychiatrist named Joseph Wolpe developed a technique called systematic desensitization. His insight was simple: you can't be anxious and relaxed at the same time. So he taught clients relaxation techniques, then exposed them to small "doses" of anxiety-provoking stimuli while they stayed calm. Gradually, the anxiety would fade.

The resemblance to somatic experiencing is striking. Both involve graduated exposure. Both alternate between distressing material and calm states. Both work with the body's physiological responses, not just thoughts.

SE practitioners and researchers describe their approach as "not a form of exposure therapy" because it "avoids direct and intense evocation of traumatic memories." But other researchers have noted that SE "includes techniques known from interoceptive exposure for panic attacks, by combining arousal reduction strategies with mild exposure therapy."

This is a pattern throughout somatic experiencing: techniques that seem novel often turn out to have clear precedents in the cognitive-behavioral tradition. The difference may be more in emphasis and framing than in fundamental mechanism.

The SIBAM Model: Mapping Experience

One of Levine's contributions is a model for understanding how experience fragments during trauma. He calls it SIBAM, an acronym for five channels of experience:

• Sensation – the raw physical feelings in your body
• Image – visual, auditory, or other sensory memories
• Behavior – impulses to move or act
• Affect – emotional feelings like fear, anger, or grief
• Meaning – the cognitive interpretation of what's happening

In a coherent, healthy experience, these five channels flow together. You see something frightening (image), feel fear (affect), notice your heart racing (sensation), have an urge to run (behavior), and understand why (meaning). All five aspects are connected.

Trauma, according to this model, fragments this coherence. The channels become disconnected or "dissociated." You might have the image of the car accident but feel nothing emotionally. Or you might feel overwhelming fear without any clear image or memory attached to it. Or a particular sensation—the smell of gasoline, say—might trigger a flood of terror that seems to come from nowhere.

SE therapy works by helping clients reconnect these channels. Slowly, carefully, with attention to what's happening in the body at each step.

Levine claims he developed this model in the 1970s. But there's a complication.

Around the same time, psychologist Arnold Lazarus developed a strikingly similar model called multimodal therapy. His framework broke experience into Behavior, Affect, Sensation, Image, and Cognition—essentially the same five elements as SIBAM, with only minor differences in terminology. Lazarus also incorporated body awareness techniques into his approach, including methods from Eugene Gendlin's "focusing"—the same "felt sense" work that Levine integrated into somatic experiencing.

Both Levine and Lazarus drew heavily on the work of Akhter Ahsen, a psychologist who in 1968 described what he called the "ISM"—a "tri-dimensional unity" of Image, Somatic pattern, and Meaning. Ahsen specifically applied this model to traumatic experiences and noted how these dimensions could become disconnected from each other.

The intellectual genealogy is tangled, and who deserves credit for what remains disputed. What's clear is that the idea of experience fragmenting into separable channels during trauma wasn't unique to somatic experiencing.

The Polyvagal Controversy

Modern somatic experiencing has embraced a theory called the Polyvagal Theory, developed by neuroscientist Stephen Porges. This theory has become enormously influential in trauma therapy circles—and enormously controversial among physiologists.

The vagus nerve is the longest cranial nerve in the body, running from the brainstem down to the gut. It plays a central role in the parasympathetic nervous system, the branch of the autonomic nervous system responsible for "rest and digest" functions—slowing the heart rate, stimulating digestion, promoting calm.

Porges proposed that the vagus nerve actually has two branches with different evolutionary origins and different functions. The older "dorsal vagal" branch, shared with reptiles, supposedly mediates freeze and shutdown responses—playing dead when fight or flight won't work. The newer "ventral vagal" branch, unique to mammals, supposedly mediates social engagement—the ability to feel safe in connection with others.

This framework has intuitive appeal for trauma therapists. It offers an elegant explanation for why some trauma survivors don't just fight or flee but instead collapse, dissociate, go numb. They're not choosing to shut down—their ancient reptilian vagus nerve is taking over.

The problem is that neurophysiological research doesn't support key aspects of this theory. Studies have shown that the dorsal motor nucleus—the brainstem area controlling the "old" vagus—has little to do with heart rate responses to psychological threat. The cardiac effects that Polyvagal Theory attributes to the dorsal vagus actually appear to be mediated by the ventral branch.

This matters because somatic experiencing therapists often explain client experiences using Polyvagal terminology. They might describe a client in a "dorsal vagal shutdown" with slowed heart rate—but the physiology underlying that description may be wrong.

Does it matter if the mechanistic explanation is incorrect, as long as the therapy helps? Perhaps not. Therapists throughout history have achieved results with inaccurate theories of why their methods work. But it raises questions about how much to trust the theoretical framework SE practitioners use to understand their clients.

The Evidence Question

So does somatic experiencing actually work?

The honest answer is: we don't know yet.

A 2021 literature review summarized the state of evidence this way: "Findings provide preliminary evidence for positive effects of SE on PTSD-related symptoms." But it went on to note that "the overall study quality is mixed," and "the current evidence base is weak and does not (yet) fully accomplish the high standards for clinical effectiveness research."

The review called for more rigorous randomized controlled trials—studies where participants are randomly assigned to receive SE or some comparison treatment, with researchers who don't know which treatment each participant received evaluating the outcomes.

This is the gold standard in medical research, and SE hasn't yet accumulated enough high-quality trials to definitively establish its effectiveness. This doesn't mean it doesn't work—many therapies that are ultimately found effective go through a period with limited evidence. But it does mean that confident claims about SE's superiority to other approaches aren't yet justified by data.

It's worth noting what the evidence situation doesn't tell us. The absence of definitive proof isn't proof of absence. Many therapists and clients report that SE has been helpful. The question is whether those reports reflect something specific to SE's techniques or whether they reflect nonspecific factors common to many therapies—a caring relationship, hope, attention to one's experience.

Who's Practicing This?

One underappreciated aspect of somatic experiencing is the diversity of practitioners.

Unlike psychotherapy, which typically requires advanced degrees and state licensure, SE certification is open to people from many backgrounds. Practitioners include licensed mental health professionals—psychologists, social workers, psychiatrists—but also Rolfers (practitioners of a form of deep tissue bodywork), yoga teachers, Feldenkrais practitioners (who teach awareness through movement), clergy members, educators, and occupational therapists.

This creates a regulatory gray area. SE is not listed as a massage modality, so practitioners aren't regulated under massage practice acts. But it's also not exclusively a form of psychotherapy, since many practitioners aren't licensed mental health professionals.

The SE training program tells participants they "are responsible for operating within their professional scope of practice and for abiding by state and federal laws." In practice, this means a licensed psychologist doing SE with trauma patients operates under very different regulatory oversight than a yoga teacher doing SE with students.

For potential clients, this means asking careful questions. What is this practitioner's background? Are they licensed in a mental health profession? What is their specific training? If you have a diagnosed mental health condition, are they qualified to treat it?

The Bigger Picture: Body and Mind

Step back from the specific controversies, and somatic experiencing reflects something genuinely important in our understanding of trauma and stress.

For much of the twentieth century, Western psychology treated the mind as a kind of computer—a processor of information that could be reprogrammed through talk therapy. Emotions were seen as byproducts of thoughts. Change your thinking, change your feelings.

But research over the past several decades has increasingly supported a more integrated view. The brain isn't floating in a vat somewhere—it's part of a body, constantly receiving signals about that body's state. When you feel anxious, you don't just think anxious thoughts; your heart pounds, your muscles tense, your breathing changes. And those physical changes can feed back into the brain, intensifying the psychological experience.

Trauma appears to involve the body in particularly profound ways. Brain imaging studies show that trauma can alter how people perceive and respond to bodily sensations. People with PTSD often have difficulty identifying what they're feeling physically—a phenomenon called alexithymia. They may feel chronically tense, or strangely numb, or both at different times.

Whether somatic experiencing's specific techniques are the best way to address these issues remains an open question. But the basic premise—that healing from trauma requires attention to the body, not just the mind—seems increasingly well-supported.

Other approaches, including some with stronger evidence bases, have incorporated similar ideas. Trauma-sensitive yoga, for instance, has been studied in randomized trials and shows promise for PTSD. Mindfulness-based interventions, which emphasize present-moment awareness of bodily sensations, have extensive research support. Even traditional cognitive-behavioral therapy has evolved to include "interoceptive exposure"—deliberately noticing and tolerating uncomfortable physical sensations.

Making Sense of the Complexity

Somatic experiencing exists at a strange crossroads. It draws on legitimate scientific observations about trauma and the nervous system. It also draws on Wilhelm Reich's theories about blocked energy and Peter Levine's mystical experiences with Einstein's ghost. Its techniques overlap substantially with established cognitive-behavioral methods, yet it markets itself as fundamentally different. Its evidence base is growing, yet remains insufficient for confident claims of effectiveness.

For someone considering this therapy, what matters most is probably not the theoretical framework but the practical questions: Does this particular practitioner seem competent and trustworthy? Am I making progress? Do I feel better over time?

These questions can't be answered by research studies. They require paying attention to your own experience—which is, in a sense, what somatic experiencing is all about.
