I was thinking about this because of the thread title "Can meltdowns be stopped by giving in?" Because I've noticed something with overload that's very interesting. It's not really about "giving in," which is why I made a different thread. But there is something that seems to affect overload:
I've noticed that certain kinds of overload are much worse when my brain is trying to "make sense" of my surroundings.
If I simply stop trying to understand things, then a few things happen. Sometimes it takes a few seconds to a minute before I can manage to stop trying to understand. The attempt to understand things can get up some momentum and be hard to push back against. But when I manage to do it, then there's like... you'd think there'd be an audible click, like when something turns off, but normally there isn't. There's just suddenly, as if you turned off a TV and the high-pitched whine stops. Or turning off anything else. It can feel as if the volume or the brightness or the clutter is turned down to something much more manageable even though none of that has changed. Things still won't make sense, but you don't feel the tension and pressure in your head resulting from trying to make sense of them. And you may even find that a meltdown, shutdown, or other extreme reaction to overload has been postponed or removed entirely from the stuff-about-to-happen list. Or that the meltdown, shutdown, etc. is less severe than it otherwise would be.
I wish it was possible to explain how to stop trying to understand stuff. For me it's pretty easy because I don't naturally try to understand. But I've known other people who do naturally try to understand, so they might find it harder than I do. What I generally do is I concentrate on some part of the sensory experience and avoid thinking of what it might be, just focusing entirely on the sensory aspects, and try to avoid thinking about anything else, including "what does this mean?" But I have no idea how hard that might be for someone whose natural experience of the world includes a brain that tries really hard to understand everything. But I suspect it can be done at least a little if the person works at it long enough, and it might be useful in terms of reducing many kinds of overload.
