"What do you notice in your body right now?"
"I don't know. Fine, I guess."
Every trauma therapist has lived this exchange. The question is the right one. The client is not being evasive. They simply have no route to the answer yet, because noticing internal experience is a capacity, not a given, and trauma is remarkably good at dismantling it. The bridge between that question and a meaningful answer has a name, and it has had one since the 1960s: the felt sense.
The felt sense is a whole-body, pre-verbal awareness of a situation, feeling, or memory: an internal sense of something that is initially vague and murky, and that becomes clearer as attention rests on it. It is not an emotion and it is not a thought. It is the body's holistic knowing of a thing before words arrive.
The term comes from Eugene Gendlin, the philosopher and psychologist whose research at the University of Chicago asked a deceptively simple question: why does therapy work for some clients and not others? What Gendlin found was that successful clients shared a habit that had little to do with the therapist's technique. They paused. They groped for words. They attended inwardly to something they could sense but not yet say, checking candidate words against a bodily feel until one clicked. Gendlin (1981) called that something the felt sense, and built his Focusing method around teaching people to access it deliberately.
Two properties of the felt sense matter enormously for trauma work. First, it is initially unclear by nature. The murkiness is not a failure of the client's introspection; it is what pre-verbal knowing feels like before it resolves. Second, it carries more than any single emotion word can hold. "The whole thing about my mother" arrives in the body as one intricate sense, and when a client finds words that genuinely match it, something shifts physically, a loosening Gendlin called the felt shift.
Trauma is stored heavily in implicit memory: in sensation, procedural pattern, and autonomic response rather than in narrative (Ogden et al., 2006). That is why clients can understand their history thoroughly and still live inside its physiology, a dynamic we unpacked in our article on top-down versus bottom-up processing. Bottom-up work needs an access point to that implicit layer, and the felt sense is one of the most reliable access points we have.
In Somatic Experiencing, the felt sense is foundational: it is the channel through which clients contact bound survival energy, track activation and settling, and notice the small internal shifts that pendulation depends on (Levine, 2010; Payne et al., 2015). A client who can find and stay with a felt sense can participate in their own nervous system's process. A client who cannot is limited to reporting on their experience from the outside, which keeps the work cognitive no matter how somatic the therapist's intentions are.
If the felt sense were easy to access, the "fine, I guess" moment would be rare. It is common, and for protective reasons worth respecting.
Interoceptive avoidance is adaptive. For a client whose internal sensations have historically preceded overwhelm, not feeling is a survival skill. The numbness did its job. Asking such a client to attend inward is asking them to reverse a strategy that worked, and their hesitancy deserves the same respect as any other defense.
Dissociation interrupts the signal. Clients who habitually leave the body under stress cannot report on a body they are not occupying. The felt sense requires a degree of embodied presence that is itself a treatment goal, not a starting assumption.
Nobody gave them the vocabulary. Most adults can name emotions. Far fewer have ever been asked to describe sensation: the difference between tight and heavy, between buzzing and trembling, between hollow and numb. Without words for it, internal experience stays undifferentiated, and undifferentiated experience is hard to stay with.
We ask too big, too fast. "What are you feeling in your body?" is an enormous question for someone with limited interoceptive access. The clinical error is not the question but the dosing. The felt sense is approached at its edges, in small amounts, at a pace the nervous system can tolerate.
The practical bridge to the felt sense is vocabulary. When a client has sensation words available, attention has something to organize around, and murky internal experience begins to differentiate. A few principles guide this work:
Offer menus, not open fields. Instead of "what do you notice?", try "is it more tight or more heavy? Warm or cool? Still or moving?" A choice between two sensation words is answerable in a way an open question is not, and even "neither, it's more like..." is the felt sense beginning to speak.
Stay descriptive, not interpretive. "Tight" is sensation. "Anxious" is interpretation. Both matter, but the felt sense lives at the descriptive level, and clients will drift toward interpretation because it is more familiar. Gently returning to sensation keeps the work in the body.
Use invitational language. "You might notice..." and "if it feels okay, see whether..." keep the client in choice. For trauma survivors, being directed into their body can echo the very experiences that taught them to leave it.
Let murky be enough. "Something in my chest, I can't describe it" is not a failed answer. It is a felt sense forming. The therapist's patience with vagueness teaches the client that theirs is allowed.
A Starter Language of Sensation
Temperature
warm, cool, hot, cold, flushed
Texture
tight, soft, knotted, smooth, prickly
Movement
buzzing, still, fluttering, pulsing, trembling
Weight
heavy, light, pressing, floating, sinking
Shape and space
hollow, full, expansive, contracted, edged
Offered as choices in session ("more tight, or more heavy?"), words like these give the felt sense something to organize around.
Described on the page, this looks simple. In session, it involves continuous judgment: reading whether attention to sensation is building capacity or building overwhelm, knowing when to deepen and when to orient away, and pacing the whole process through pendulation and titration. Those are trainable skills, and they are taught experientially, because the felt sense is something a clinician needs to know from the inside before guiding anyone else there.
At TTI, the felt sense and the Language of Sensation are core curriculum in our Somatic Experiencing and Trauma Therapy Training with Alison Leslie, LCSW, a credentialed Somatic Experiencing Practitioner. The two-day, on-demand training walks through the felt sense alongside the Threat Response Cycle, pendulation and titration, the Trauma Vortex and Counter Vortex, somatic boundary work, and co-regulation, and it is experiential throughout: you practice each technique as you learn it, so the felt sense becomes something you have contacted rather than a concept you have read about. The training has no prerequisites and carries 8 CEs (NBCC and ASWB/ACE).
For EMDR-trained clinicians, felt sense skills strengthen exactly the places the standard protocol assumes capacity: Phase 2 preparation, the body scan, and moments in reprocessing when a client cannot verbalize what is happening. Our article on integrating EMDR with somatic practices explores that intersection in depth.

I'm Exploring the Somatic Trainings →An emotion is typically nameable and categorical: anger, sadness, fear. The felt sense is broader, vaguer, and more particular all at once: the whole bodily sense of a situation, which may contain several emotions plus meanings that have no emotion word. A client can name an emotion instantly; a felt sense takes a moment of inward attention to form, and its initial unclarity is part of what identifies it.
Eugene Gendlin, a philosopher and psychologist at the University of Chicago, introduced the term through his research on why psychotherapy succeeded for some clients and not others. He developed the Focusing method to teach deliberate access to the felt sense (Gendlin, 1981). The concept has since been adopted widely across somatic approaches, including Somatic Experiencing.
Numbness is information, not absence. "Nothing" can be attended to like any other internal experience: where is the nothing, does it have an edge, is it more like fog or more like a wall? Approached this way, numbness often begins to differentiate. If it does not, that is a signal to build safety and interoceptive capacity more gradually rather than to push harder, and pacing skills like titration exist for exactly this situation.
They are related but not identical. Interoception is the perception of internal bodily signals: heartbeat, breath, tension, temperature. The felt sense uses interoceptive capacity but goes further, integrating those signals into a holistic, meaning-laden sense of a situation. Interoception is the instrument; the felt sense is the music.
