For as long as I can remember, ever since I had my own room, one thing that absolutely drove me insane was my mom quietly opening my door. I know she means well. She’s checking if I’m sleeping, and she opens it so softly precisely so she won’t wake me if I am. And if I’m actually asleep, it never does wake me. But it’s when she does it while I’m just out of the shower, or getting changed, or lying in bed scrolling, when I sense the door being eased open, something in me just snaps. My entire nervous system dysregulates in an instant. Like every cell in my body goes on high alert before I even consciously register what’s happening. It honestly pisses me off so much, and what makes it worse is that I can’t even fully explain it in the moment. I’ve told her to knock, multiple times, and sometimes she does. But you know how parents are about knocking. To them, it isn’t their child’s room. It’s their house.

Anyways, the point is, I finally figured out why.

It took me longer than I’d like to admit. Because on the surface, what is there to figure out? Your mom opens your door. Big deal. Except it is a big deal, and it has always been a big deal, and I could never articulate why without feeling ridiculous. The same thing happens when I’m startled out of sleep. One time I woke up and my ex was just sitting in my room and it scared the shit out of me, my nervous system took literal days to settle from that. Days. From someone just being there. And I remember thinking, why am I like this, why is my body so dramatic, why can’t I just be normal about these things.

But it isn’t dramatic. And I’m not just being difficult. There’s a reason.

The real why. The reason I can’t stand my room being opened without warning, without consent, without any sound except the soft betrayal of a door, is because that is how he used to do it. Predator behaviour. He’d open it quietly, so deliberately quietly, so as not to wake me or anyone else up. So no one would know. And then he’d come in and lay his dirty hands on me. I was just a girl. I didn’t know the world. I didn’t know what was happening to me or that I was allowed to make it stop or that any of this was something I could tell someone about. His claws were too sharp for someone who didn’t even know she needed to protect herself.

And yet my body knew. Even when I didn’t.

That’s the thing about trauma. You don’t get to decide what it latches onto. It doesn’t care how many years have passed or how much healing you’ve done or how far removed your present life is from that small, terrified version of you. My body catalogued that sound. The specific quiet of a door being opened by someone who doesn’t want to be heard. And now, 17 years later, every time I hear it, it sounds exactly the same. The threat response is identical. It doesn’t matter that it’s just my mom on the other side. My nervous system doesn’t wait to find out.

I lock my room a lot now. Not because I’m hiding anything, but because I can’t afford to be thrown off like that. When it happens it sets me off so badly that it takes a long while to feel okay again, like genuinely okay and not just functioning. It happened recently and I sat with it afterward, trying to trace back why something so seemingly small was doing this to me. And the further back I traced it, the darker it got, until I reached the reason. The harrowing, awful, very specific reason. The one no little girl should ever have.

Because even a door opening without your consent is a nightmare when your body has been trained to fear what comes after. It’s going to war with no warning. Standing in a room not knowing if the worst is coming or not, and just having to wait and see, and having no power over any of it. Your body remembers that powerlessness. That’s what it’s reacting to. Not the door. Not your mom. The powerlessness.

And now you’re exhausted. Tired of being on edge. Tired of that low hum of alertness that never fully goes quiet. Tired of flinching at things that should be nothing. Tired of explaining yourself or not being able to. Tired of a body that still hasn’t forgiven the world for what one person did in it, a long time ago, when you were just a girl who didn’t know any better.

17 years on and the door still sounds the same.
