I don't mind questions, but trying to explain the experience of DID can be difficult, so please bear with me.
The "voices" could be thought of as "thoughts", although they are thoughts that don't seem to belong to who "I" am. And, there are feelings that don't belong either. An example: I love my husband and I want to spend time with him. But, there is another part that has only recently become aware of the present again and is kind of stuck in trauma time (it was active when I was a child/teen, but not as an adult so it had not been around when I married my husband), and It does not like or trust men. So, when this particular part is close to the "front" or surface and sees my husband It becomes very upset and agitated. I don't necessarily have to switch to this part, I will hear It say things like "Be careful. Get away..." And, I may find it very uncomfortable to hug or be close to my husband and may leave the room. On the other hand, I have a little one that adores my husband and will become very excited when she sees him and will crawl up into his lap.
Have you always had these kind of internal communications?
I have, but a year ago I wouldn't have known it for what it was. I have always carried on discussions in my head and always been able to have lots of different view points. But, I didn't think this was unusual until my T said that most people don't have this. Yes, they carry on discussions with themselves, but it is with themselves and while they might list out pros and cons they don't come at problems with different point-of-views. I have years of journals which contain all sorts of back and forth discussions with what I at one time called the holy spirit, now I am aware of who it is.
I am asking because I don't necessarily feel like I have internal voices though I can sense reactions and sometimes thoughts. But everything I have read talks about the "hearing" of internal voices so then I start to think I am just crazy.
Some people don't start off hearing their other parts. The DID system is created to protect itself. It can take years to develop internal communication between parts. Some suggest using a journal to write in at different times of day and places. Talk to yourself, and tell them that there is a journal and they can write anything in it they want. Tell them you want to talk to them.
I've probably answered way more than you asked.
You are welcome to ignore what I am about to say, but I worry about you when I read your other posts and then read this one. The first step in treatment for those with Dissociative Identity Disorder is stabilization and internal system communication. Not trauma work. Without building a relationship with those other parts of you, you may be re-traumatizing those hurt parts by reliving the trauma. It will just cause more dissociation. Trauma therapists generally agree that a patient should have some ability to stay co-conscious with their alters when doing trauma work. The first stage, stabilization (not trauma work), can take up to two years. DID treatment is not a race, but a really long marathon.
