Does anyone else use a physical action to intentionally trigger a dissociative state?

I'm trying to make sense of my relationship with what I can only describe as dissociation, and it feels a bit different from what I usually read about. For many, it seems like something that just happens to them, like a switch flips and they're gone. For me, it's always felt like a very active process, a tool I have to deliberately turn on.

I have this specific, repetitive physical movement I do with my arms and hands. It's a kind of stim, I suppose. But its main function is to act as the key to unlock a very deep, immersive daydream state. It's strange, it feels like the physical motion generates a kind of static or buzz in my brain, and that buzz is what allows me to completely detach from my surroundings and enter a fully-realized internal world. The physical part is essential; without it, I can't achieve that full sense of detachment.

I've done this since I was a kid. It's my go-to method for escaping. Anytime the real world felt boring, or frustrating, or just too much, I could just start this physical process and 'check out' completely. It's a very effective off-ramp from the present moment. I can do it for hours, just existing in this other space where I'm in control.

It became so practiced that I even developed a "stealth mode" for school, where I could trigger the dissociative fantasy without the big physical movements so people wouldn't notice.

I guess I'm just wondering if this resonates with anyone here? This idea of dissociation not just being a passive state you fall into, but a practiced, almost ritualistic skill that you actively initiate with a physical trigger. It feels like more than just zoning out, because of how deliberate the entry-process is. Just trying to understand if other people have a similar 'on-switch' for their dissociation.
