only your own treatment provider can answer what and how this process is supposed to work for you.

that said Im willing to take a guess based on how my own internal system was...

my alters even those I didnt know existed were able to know what was going on with me. other wise they would not have known when to take control and do their sense of agency (job, purpose, reason for being created and so much more)

example if rainy had no idea that I was feeling scared during a thunderstorm, she would not have known to take control when thunder storms were triggering me to do her job of getting out of the rain, into dry clothing, make a warm and soothing snack, cuddle up with a blanket and toy.

some how some way she was able to know when it was time to do her part, do what and why she was created.

my therapist and I called what ever it was that gave her this ability my "filtering down to her"

we used this filter when ever we wanted Rainy to understand what was going on.

my point and taking a guess is that maybe this is what your treatment provider is doing.... explaining the integration process thats going to happen with you, in a way that the others will understand too. if you have the ability to know what your alters are doing, thinking or saying, drawing and thinking about what you are doing is a way to communicate whats going on, in a way that does not require you to get triggered and dissociate so that others will take control.

in other words its a more natural approach instead of all that over dramatized stuff you see in the movies and in books.

again this is only a guess based on how my own internal system was. to get your questions actually answered directly related to you and your process you will need to talk with the treatment provider that is doing this with you.
