I'm not sure how common this is amongst the plural community, but we experience this kinda odd phenomenon that I like to call "temporary splits".
Basically, when we split, we tend to gain 2-10 fragments. Said fragments will experience the pain of the stress, but after they are done with the feelings, they will sort of fuse back into the headmate they'd split from or into someone else entirely. Which can cause our identities to be a bit unstable since we do split like this quite a bit.
This (seemingly) only happens during more "mild" stress like confrontation & being overstimulated.
"Bigger" stresses (again, seemingly) causes "permanent splits". Where fragments cannot fuse, and end up either staying as fragments or grow to be more complex.
At least that's what I've been noticing anyways. It's a little bit hard for me to properly analyze our splitting patterns whenever dissociation has me a bit drugged out-
