I know what your saying, I go through them changes also. For me it's like perceived fear that's the threat, a mental trigger. Being mental, it's a focus, not like an incidental trigger through my day.
Like amanda said about walking in the dark, I switch through the many versions of each of fight, flight, freeze, and fawn instincts- depending on whose jobs it is to deal with what. This also applies to social and life situations, looking for an other to step up to handle the trigger. It can get fearful having to confront another person and say "hi", to like strangers. Expressing myself is fearful, too.
It's like one would step up and say "not me" "no you do it", then the next, then another....like a revolving door. Usually the body dazes out and twitch with each switch, like going through a Rolodex till it randomly stops at the unlucky winner.
Lol.....ya, that so freaking funny when that happens. Omg, we drank a bunch of coffee this morning! I feel so giggly and warm and fuzzy!
Well, whatever was being said just faded away, but I know it's about switching! And we just switched, why? I no idea why, but it feels good to get out. It's been a day and he just took over. We switch a lot. I guess it's because we do.
Switching is just what we do! Luv!
