yes, we can keep secrets from each other. it's not always effective, granted, and we usually don't want to, but like. if a system already has dissociative barriers for trauma it does make sense to be able to utilize those occasionally for less important or painful stuff. also sometimes it happens accidentally? like we get something and someone who hasn't fronted in a while comes out a year later and didn't know, and they get so excited. it's cool to be able to "treat yourself" multiple times in a row just bc of how your brain works lol
for us, it depends on the headmate. some of us struggle to hear others when in front, and have to focus quite hard. usually these are the same people it is harder to reach when they are in headspace or further back. overall, we have pretty decent communication, and for us it seems that comes at the cost of hearing chatter when we don't necessarily want to. at least it's usually funny :)
we would describe this as overlapping heavily with intentional communication as described in question 2. that said, many of us can have private thoughts and opinions and feelings. the rest of us will usually get a vibe off of them (x might not be feeling well, x seems sad or angry lately, etc.)
we usually front in groups, with one or a few primary fronter(s) and several in co-con to varying degrees. anyone in that group would definitely know, and how close they are to front would determine how much their personal reaction affects the body or us as a whole. people in headspace wouldn't notice to my knowledge
a little bit of both! we've always talked to ourselves and didn't even realize it was system communication (as is common since singlethood is presumed). it's usually easier in our case for the fronter to talk out loud and anyone else to respond internally. now is also probably a good time to note that we rarely think in words, and most responses (and thoughts in general) are in pictures and feelings that we can translate to language if needed. so if I say a headmate responded with a sarcastic comment, it was probably more the feeling of rolling eyes plus a bunch of other pictures and feelings that instantly get the point across.
that is a really good question. I think I would have to say yes, since there are headmates we know are active but we don't know what they are up to or thinking about. kind of like knocking on a sibling's door and you hear movement but they don't answer.
yes, but the ease and effectiveness of that action very much depends on the person fronting. to make it easier, we built a section of headspace that looks like our therapist's office, and a fronter visualizing themselves there can easily block heavy conversations from reaching ears that shouldn't hear it.
it is. many that we do not share were not by choice, as is common in complex dissociative disorders. some have chosen to share their uncomfortable memories with each other as a solidarity thing, especially those who have similar compartmentalized experiences. over time we have been able to share our joy and natural behaviors with each other (having previously had any Autistic traits blocked off in specific alters) and that has been good. we also make new memories together and keep important daily knowledge accessible, like who is ok to reach out to and how to do our job.
our inner world is largely shared, but some portions are private. each headmate is allowed to bar entrance to others into their private space if they want to, or to share it if they feel comfortable. there is plenty of shared space like a cozy meeting room, play spaces, and nature areas that people can socialize in if they choose without compromising their private space and time. everyone gets to build and decorate and change their space however they like, for shared spaces we use a casual voting system.
we try to make sure every headmate feels welcome and safe at home. this means we have a wide variety of clothing types and toys and stuff that everyone likes. everyone has a chance to be themselves as fully as our physical form allows. not everyone takes advantage of that, and there are rules (don't make a big body change without general agreement, cause as little harm as you can, etc.). but overall yeah we can be ourselves and we are finally not ashamed of that. helps that we have a wonderful partner living with us who encourages everyone to take their time in front and be themselves. all that to say hell yeah shapeshifting is fun
