Yep. Currently working through Autistic Burnout, and one of my symptoms is Dissociation. Whenever I'm slightly stressed or concentrate hard on something, it kicks in. My head feels a bit "spinny", but I'm not dizzy; I feel a bit "high", but without the pleasant buzz of weed; when I move around, I kind of feel like a floating balloon on a string being pulled round by a toddler. My interoception (internal sense) is terrible at the moment, so I don't get body maintenance signals like need to pee or drink, until I'm almost desperate, and I feel emotionally numb - I mostly seem to only "feel" strong negative emotions, positive ones if felt at all are pretty distant. I also get visual snow - like TV static in my vision - and a "laggy" feeling, which is often independent of, but somehow connected with the dissociation, which feels like living in a 3D game with too low a frame rate - my perception of my movement becomes stuttered, almost like there is a strobe light on, and it feels like I'm moving through treacle. It's a bundle of fun.
Edit: I'd also intended to say, but I got distracted by my cat asking for food, that I hope you feel better soon. I'm sorry you are having to live through this. I find for me, it takes a few days to a week to wear off after I've been stressed - it seems to peak a day or so later, and then peter out over a number of days, as long as I avoid stress. I hope you can avoid your trigger.
