Understanding Triggers vs. Glimmers
Glimmers & Triggers: How Your Nervous System Tries to Protect You
Most people can name their triggers instantly—a sharp tone, conflict, feeling ignored, uncertainty. But when asked about their glimmers, many people pause. This isn’t because they’re doing anything wrong. It’s because the nervous system of someone who has lived through relational trauma or chronic stress becomes finely tuned to detect danger, not safety. That hyper‑awareness is an adaptive response, not a personal flaw.
What Is a Trigger?
A trigger is anything—inside or outside of you—that signals a potential threat to your nervous system. Even when no real danger is present, your body reacts as if there is. Triggers can activate:
Anxiety or panic
Emotional overwhelm
Shutdown or dissociation
The “brain goes blank” feeling during conflict
Fight, flight, freeze, fawn, or flop responses
These reactions are your body’s way of saying, “I’m trying to keep you safe.” They exist because your nervous system learned—often through painful experiences—that vigilance was necessary for survival. The issue isn’t that triggers exist; it’s that trauma can cause the system to become over‑focused on them.
What Is a Glimmer?
A glimmer, a term introduced by Deb Dana, is the opposite of a trigger. It’s a small moment when your nervous system senses safety, connection, or ease. Glimmers are subtle:
Warm sunlight
A kind smile
A calming song
A moment of being understood
Finishing a small task and feeling proud
Most people experience glimmers every day, but trauma can make them harder to notice. And what we don’t notice, we don’t integrate. As Bessel van der Kolk reminds us, trauma lives in the body—not just in thoughts. Healing requires helping the body recognize safety again.
Why Both Matter
Triggers narrow your focus and pull you into survival mode. Glimmers widen your focus and help your system soften. Both can exist at the same time. Healing isn’t about eliminating triggers—it’s about building flexibility, the ability to shift out of survival mode when safety is present.
Think of your nervous system like a rubber band. If it’s stretched tight all the time, it loses elasticity. Glimmers help restore that elasticity so you can respond more effectively when real challenges arise.
A Simple Daily Glimmer Practice
Try this once a day:
1. Ask yourself:What felt even slightly calming, pleasant, or grounding today?
2. Pause for 10–20 seconds. This pause helps your body register the experience, not just your mind.
3. Write it down. Over time, you’ll build a personal “glimmer map.”
This isn’t forced positivity. It’s nervous‑system training. As Janina Fisher emphasizes, trauma responses are adaptive survival strategies—not signs of weakness.
Holding Both: The Pro‑Dependent Perspective
From a pro‑dependent lens, triggers and glimmers are not opposites to battle—they’re signals from a nervous system doing its best to protect you. Triggers show where you’ve been hurt. Glimmers show where healing is possible. You don’t have to choose one or the other. You learn to hold both with compassion.
When a trigger arises, you can acknowledge it without judgment. And afterward, intentionally shifting your attention toward a glimmer—even a tiny one—helps rebalance your system. Over time, glimmers soften the intensity of triggers and create more internal stability.
You are not “too sensitive.” You are not “overreacting.” Your nervous system is responding exactly as it learned to respond.
And you also have the capacity to create new patterns—slowly, gently, one glimmer at a time.
You are both the keeper of your triggers and the creator of your glimmers. Learning to honor both is where healing begins.
