One moment you’re fine. The next, your chest tightens and your breath gets shallow. Nothing dramatic just happened—maybe someone canceled plans, or you caught an expression on someone’s face. But suddenly, you’re flooded with emotion that feels way too big for the moment.
This isn’t about being “too sensitive” or “overreacting.” Our minds and bodies are designed to learn from experience—and sometimes they apply lessons from one situation to another, even when it no longer fits.
How experiences get stored
When something significant happens to us—especially something overwhelming, frightening, or deeply meaningful—our brains don’t just file it away like a document in a folder. The experience gets stored in multiple ways: as thoughts and narrative memories, but also as sensations, emotions, images, and even physical responses.
Most of the time, this works beautifully. You learn that fire burns by touching a hot stove once, and your body remembers to pull away from heat before your conscious mind even processes the danger. You develop an intuitive sense of which people feel safe and which don’t, based on countless interactions stored below conscious awareness.
But sometimes experiences get stored in ways that become problematic. Maybe you learned that raised voices meant danger, so now any conflict activates your alarm system. Maybe you learned that people leave without warning, so now any shift in someone’s energy feels like impending abandonment.
When the past shows up uninvited
These stored experiences can get triggered by surprisingly small things—a particular tone of voice, a familiar smell, a certain facial expression, even a specific time of day or season. Your nervous system picks up on a cue from the past, and suddenly you’re reacting to what was, not what is.
This might look like having a panic attack during a routine medical appointment because the smell of antiseptic reminds your body of a traumatic hospital experience. Or feeling inexplicably sad every December because that’s when something difficult happened years ago. Or finding yourself unable to speak up in meetings because some part of you still remembers when being seen meant being criticized.
The confusing part is that this often happens without conscious awareness of the connection. You just know you feel terrible, or scared, or shut down, and you can’t figure out why the current situation feels so threatening.
Your body is trying to protect you
From your nervous system’s perspective, this isn’t a malfunction—it’s a feature. Your body learned to recognize certain patterns as dangerous, and it’s doing its job by trying to keep you safe when those patterns show up again. The problem is that your body can’t always distinguish between then and now, between real current danger and situations that just remind it of past danger.
This is why you might feel your heart racing during a perfectly safe conversation that happens to echo an old argument. Or why you might feel an overwhelming urge to leave a party where nothing bad is actually happening, but something about the dynamics reminds your system of times when groups felt unsafe.
Your body is essentially saying: I remember this. Last time something like this happened, we got hurt. I’m getting us ready to fight, flee, or freeze—just in case.
The storage problem
Sometimes the experience was too big, too fast, or too early for your system to process. So it didn’t get resolved—it got stored.
When experiences aren’t fully processed, they can remain active in your system, ready to be triggered by anything that reminds your body of the original situation. It’s as if part of you is still back there, still trying to handle something that never got resolved.
This is particularly common with childhood experiences, because children’s nervous systems are still developing and they often don’t have the resources to process overwhelming events completely. But it can happen with adult experiences too, especially during times of high stress, loss, or trauma.
How the past shows up in therapy
People often come to therapy feeling confused about their own reactions. They know something is off, but they can’t quite put their finger on what. A successful professional who can’t stop feeling like they’re about to get in trouble. Someone who panics whenever they have to make decisions, even small ones. A person who shuts down completely when anyone expresses disappointment.
Sometimes the connections to past experiences are obvious. But often they emerge gradually, as we start paying attention to what triggers certain responses and what those responses remind us of. The goal isn’t always to uncover specific memories—sometimes it’s about helping your nervous system learn that the past is over, and you have more options now than you did then.
Different approaches to stuck experiences
There are various therapeutic approaches that help process experiences that feel stuck between past and present. Some focus on the narrative—helping you make sense of your story and how past experiences connect to current patterns. Others work more directly with the body and nervous system, helping stored sensations and responses complete and release.
Our understanding of how trauma affects the body has grown tremendously in recent years. Bessel van der Kolk’s “The Body Keeps the Score” details recent research showing how traumatic experiences get stored not just in memory, but in the nervous system—explaining why the body can react to reminders of past events as if they’re happening right now.
EMDR (Eye Movement Desensitization and Reprocessing) helps the brain process traumatic memories so they stop feeling so immediate and overwhelming. Somatic approaches work with the physical sensations and responses stored in the body. Parts work, like IFS, helps different aspects of your experience communicate and find resolution.
What you can notice on your own
Even without formal therapy, you can start paying attention to moments when your reaction feels disproportionate to what’s happening. Instead of judging yourself for “overreacting,” you might get curious: What does this remind me of? When have I felt this way before? What is my body trying to protect me from?
Sometimes just recognizing that you’re responding to an echo from the past can create some space around the experience. You might still feel it—but now, part of you knows: this feeling is about then, not now.
You can also experiment with grounding techniques that help your nervous system recognize you’re in the present. Feeling your feet on the floor, noticing what you can see and hear right now, taking slow breaths—these can help interrupt the loop between past and present.
When patterns feel overwhelming
If you find yourself frequently hijacked by reactions that seem to come from somewhere else, or if past experiences feel very much alive in your daily life, therapy can provide a safe space to explore and process what’s been stored. Sometimes we need support—not to rehash the past, but to help our bodies feel that it truly is the past. That now is different. That we’re safe enough to let go.
Working with trauma doesn’t always mean diving into painful memories. Often it’s about helping your body feel safe enough in the present to let go of old patterns of protection. It’s about creating new experiences that teach your nervous system you have more resources and options than you did back then.
I refer out for EMDR–but understanding how past experiences live in the present shows up regularly in sessions. Sometimes the most healing thing is simply having someone witness how much sense your responses make, given all you’ve been through.
