Part 1 of 3 — introducing a new way to map what your nervous system is doing, and why
The Problem With “Just Think Positive”
Have you ever known you were safe, but your body just… wouldn’t get the memo? Your heart’s racing during a normal conversation. You go numb during an argument that isn’t even that big a deal. You catch yourself over-apologizing to someone who has power over you, even though nothing is wrong right now.
That’s not you being dramatic, broken, or “too sensitive.” Your body learned, at some point, that this reaction kept you safe. And bodies don’t let go of a survival strategy just because your logical brain says, “we’re fine now.” You can’t think your way out of a nervous system response. You have to help your body feel safe, from the inside.
To do that, it helps to know what’s happening inside you, and why. That’s what this whole series is about.
The Old Map: A Ladder
For years, the go-to way to explain this was something called the Polyvagal Ladder, developed by therapist Deb Dana based on Dr. Stephen Porges’ Polyvagal Theory. Picture a ladder with three rungs:
- Top rung: calm and connected — you feel safe, present, able to think clearly
- Middle rung: fight-or-flight — your body’s revved up, ready to defend itself or run
- Bottom rung: shutdown — you go numb, foggy, or collapse inward
It’s a helpful starting point. But real life doesn’t move up and down a straight ladder. You can feel three things at once. You can look calm on the outside while your insides are a mess. A ladder can’t capture that.
A Better Map: Overlapping Circles
The field’s next attempt was a Venn diagram: three overlapping circles (Relaxed, Mobilized, and Immobilized) where the overlaps represent blended states, like feeling playful (a mix of calm and energized) or freezing (a mix of energized and shut down).
This is closer to the truth; our states do blend. But it’s still missing something: there’s no sense of direction. If you’re standing in one of those overlaps, which way is “more dangerous”? Which way is “back to calm”? The circles don’t tell you.
My Map: A Compass, Not a Portrait
That gap is why I created the Autonomic Survival Matrix (ASM): a grid with two directions you can track in real time:
- Left to right: how much danger your body senses, from safe on the left to high alert on the right
- Bottom to top: how much energy your body is spending, from resting and recovering at the bottom to fully fired up at the top
Every state you can be in — calm, people-pleasing, panicked, frozen, shut down — has a spot on this grid. And because it’s a grid, not just a list, you can see where you are right now and which direction leads back to feeling okay.

The Five Zones

It’s Not Either/Or: It’s Both/And
Here’s something that might surprise you: the old belief was that your body’s “go” system and “rest” system work like a seesaw, one has to switch off for the other to switch on. Newer science shows that’s not quite right. Both systems can fire at the same time, blending together to create complicated in-between states.
That’s what’s happening in Fawn (calm on the outside, defense mode underneath) and Freeze (go-power and stop-power clamped together at once). It’s also what’s happening in some of our best moments, like the specific kind of “safe” excitement you feel during playful competition or dancing, or the deep ease of intimacy. Both of those are your calm system and your energy system working together, not against each other.
Trauma Can Rewire the Map
Here’s the part that matters most, maybe: your past experiences change how your body reads the present. Something that should feel safe can get hijacked by an old survival pattern.
- If rough play or physical harm is part of your history, playful roughhousing today might instantly flip your body into fight-or-flight, even if you know, logically, you’re safe.
- If you’ve experienced sexual assault, a partner’s gentle touch might trigger an instant shutdown response, even with someone you trust.
This isn’t a flaw in you. It’s your body doing what bodies do: protecting you based on what it’s learned. Which brings us to the most important idea in this whole piece:
You Can’t Map an Event. You Can Only Map Yourself.
There’s no universal chart that says, “public speaking = fight-or-flight” or “hugs = safe & social.” Two people can have wildly different bodily reactions to the same moment because their nervous systems learned different lessons from different histories.
So instead of asking “why did this happen to me?”, try asking your body two questions:
- How did my body adapt to keep me safe in this moment?
- What do I need right now to help my body feel safe again?
That’s the value of this map: not labeling what happened to you, but understanding what your own body is doing about it, so you can gently guide yourself back toward connection.
Up next, in Part 2: we’ll dig into the “survival loop”: the difference between a stress response that completes and lets go, versus one that gets stuck in a trap.
A Note on Sources
This piece builds on and responds to existing frameworks in the field, especially Deb Dana’s Polyvagal Ladder, the Polyvagal Institute’s Venn diagram, Pete Walker’s writing on the “5 F’s” (including Fawn), and current research on how the nervous system’s branches can activate together rather than one shutting off for the other.
