IFS I think can confuse things with DID, because the parts we have are created differently and serve differently purposes and behave differently, and the way we interact wih them is part of our pathology.
I think of my brain a bit like a house, and the individual rooms are my parts. Mostly, I’m chilling out in the lounge. That’s the most usual, authentic me, or the ‘host’.
Other parts live in different rooms. So, I have one in the kitchen, and it’s open plan, so we communicate with eachother fairly easily and consistently, and she can tell me what she’s thinking without always having to front. I can keep chilling in the lounge and be in charge and simply speak to her across the counter.
Other parts that I share some limited co-consciousness with are in seperate rooms, with the door slightly ajar. We can yell at each other through the door sometimes, but mostly the only way to know what’s going on in that room is for that part to take over, because they aren’t quite ready to leave the door open and have a free flow of information yet. And crucially, with DID, that part keeps its own memories stored in their room, so I don’t have free access to that , we have to communicate with each other to share that kind of information.
Then there’s parts that keep the door to their room shut. We don’t have co-consciousness, I don’t know what goes on in that room. When the part hears a certain alarm, they take over, and I’m in the lounge completely shut out.
The goal is to try and build trust with those parts to slowly open the door a bit so that we can share information, so that I can see what’s happening in their room, and so that they can see what’s happening in the rest of the house. And then ultimately, achieve integration with all my parts, so that the whole house becomes open-plan, and there are no walls between the parts.
Definitely I know people aho have spent years with a different part sitting in the lounge playing host for years, only to have that part retreat to a more private room as the person heals and their more authentic self is allowed to occupy the lounge. That seems to happen when the person has been living in a stressful environment. When their environment becomes more manageable, the authentic self gets to chill out in the lounge with the tv remote!
Weird analogy, but it worked for me.
