[I posted this on the Dissociative amnesia forum as well, but am posting it here again on the advice of another]
The boyfriend of a friend of mine witnessed something very traumatic about 5 or 6 years ago. I'm not sure how quickly he managed this, but he repressed the memory. The only time that he remembers it is when he's asleep. This is when/how he told my friend about it. It wasn't just sleep talking though. From what my friend has told me, he seems like he's conscious. This happens quite a lot from what I can gather. He goes into this semi-conscious state when he's sleeping. Not only that, but he also has more than one persona when he's in this conscious sleep state. These "sleep selves" vary in what they are like. From what I know, one of them used to be quite different to his awake personality, but has been adapting and acting more like him. Another one is more childlike, he has gaps in his knowledge of language and understanding. There's also another persona that is completely and openly honest with my friend. He was brought up to hide how he feels, but when he's asleep and in this state, he'll tell my friend whatever is on his mind. I might be a bit mixed up with the details of what each persona is like, but I'm pretty sure there are 3 of them. Maybe 4. The point is, one of the personas (which one it is I can't remember) can remember this traumatic event. Not completely consciously, but enough to trigger the memory if he is allowed to think about it.
What confused me most about this is that the multiple personalities are only active when he is asleep. I've heard of DID/MPD, but never heard of it only manifesting when someone is sleeping. My friend seems to be okay with the sleep selves, she's just really worried about the repressed memory. He's not really in a state to handle it right now and because of cultural and money based factors, he's not really able to see any kind of professional. So, she spends a lot of time talking to him, whilst he is in this conscious sleep state (or any of the other sleep personas) making sure that he doesn't remember what happened. Does anyone know what this is (more so the multiple persona sleep thing)? Also is there any advice that anyone has for either issue?
