Before the Lights Go Out

The vision goes first.

Not dark, exactly — more like someone turned the focus dial slightly wrong. Everything goes soft around the edges, like looking through early-morning fog that hasn't burned off yet. The overhead lights, which were fine a moment ago, suddenly seem too bright. Too harsh. Too much.

And then someone is talking.

You know this because you can see their mouth moving, you're tracking their face, you're nodding. But the words are arriving wrong. They're coming through a long tunnel — delayed, muffled, landing after the moment they should have. Or they're not landing as words at all anymore: Wah WAH wah. Charlie Brown adults, fully formed sound with no meaning attached.

You're standing there staring. Nodding. Feeling like an idiot.

That's the pre-dissociation window. And learning to recognize it — to catch those few seconds before the nervous system tips over completely — is one of the most important survival skills I've built.

For some people, dissociation just happens. There's no warning, no on-ramp — you're present and then you're not. But for others, there's a window. A few seconds, sometimes a minute or two, where the nervous system is clearly struggling to maintain connection before it finally lets go.

The visual changes are physiological — not metaphorical, not imagination. When the nervous system is under severe stress, it pulls resources from higher processing centers and routes them toward survival. Visual processing is one of the first things to degrade. The clarity drops. The edges soften. Lights seem to intensify because the sensory gating — the process that filters what's important — starts to come apart.

The same thing happens with sound. Voices distort. They come through at the wrong speed, or they stop resolving into language. The auditory processing centers aren't receiving the same support they normally get, and meaning-making is one of the most resource-intensive things a brain does. When the system starts rationing, language comprehension is one of the first casualties.

So if you've been in a conversation and suddenly the words stop making sense — you're not stupid. Your brain is redirecting traffic to keep you alive.

I want to name the shame layer specifically, because it's the part that made all of this doubly painful for a long time.

Standing there, not understanding words, nodding at things I couldn't process — the narrative running underneath that experience wasn't my nervous system is struggling. It was: I'm an idiot. Something is wrong with me. Why can't I just follow a simple conversation?

The shame comes fast and it comes hard, and it's there in real time — layered on top of everything else the nervous system is already trying to manage. Not only are you disappearing, you're also blaming yourself for disappearing.

That shame response is learned. It's not an accurate read of what's happening. What's actually happening is your nervous system is doing something very specific — something it learned to do — to protect you from being overwhelmed. And you are standing there trying to function through it, which takes everything you have. The fact that you're still upright, still nodding, still trying to stay in the room — that's not failure. That's extraordinary.

When the window closes, there are usually two destinations.

Sometimes the nervous system tips into a flashback — an intrusion of the past into the present, where something from before arrives in the body as if it's happening now. The fog lifts and you're somewhere else, running old material on current circuitry.

And sometimes — the thing that's hardest to describe to someone who hasn't experienced it — there's just nothing. All the lights turn off inside of me and there's just... nothing. Just black. Not unconsciousness exactly. Not sleep. More like everything that makes you you — the sense of self, the emotional texture, the interior sense of being present — simply exits the room, and what's left is the shell of a person going through the motions.

Both destinations are the nervous system's attempt to protect. Both are real. Both are survivable.

And the coming-back is real too. Even when it doesn't feel like it — even when the nothing feels absolute and permanent — the lights always come back on. You have come back before, every single time. You will come back again.

The most useful thing I've found for the pre-dissociation window is a sensory anchor — something you practice when you're not in distress so that the nervous system knows the path. Here's how to build one:

1. Identify one sensory anchor that tends to cut through for you. Cold is common — ice water on your wrists, splashing cold water on your face. A sharp scent works for some people. Pressing your feet hard into the floor. Holding something with a distinct texture. There's no universally right answer — this is yours to discover.

2. Practice it when you're calm, on an ordinary day. Not as a crisis intervention — just to create the neural pathway. The nervous system learns by repetition. The more times you reach for the anchor in safety, the more available it is in crisis.

3. When the warning signs arrive — the fog, the tunnel, the lights too bright — don't fight it. Trying to force yourself back to presence usually accelerates the process. Instead: reach for the anchor. And say to yourself, quietly or out loud: I know where I am. I know when I am. I am coming back.

You are coming back. You always do.
