Trying to classify S's conversations

Following on from my previous post, I've tried to list all the different types of conversation:

1) With imagined people: You only hear her side of the conversation. Inbetween there is silence when she is 'listening' and then she will respond.The conversation will generally be lucid and coherent (in its own terms) with sometimes quite sophisticated vocabulary and syntax.

2) With imagined people: You hear both sides of the conversation. The conversation will generally be lucid and coherent (in its own terms) with sometimes quite sophisticated vocabulary and syntax.

3) With imagined people: You hear both sides of the conversation, though the other person's contribution often includes nonsense sounds or syllables, almost as if she can't be bothered to put too much effort in.

4) When following a conversation (with friends and family): she will contribute the odd word, phrase or occasionally sentence which is an entirely appropriate response.

5) When following a conversation (with friends and family): she will respond but what comes out is confused and seems to have little relationship to what is being discussed.

6) With me and her daughter, S will often have usually short but perfectly normal conversations. She rarely pauses to 'find' words and never uses the 'wrong word'.

7) Occasionally she will have longer conversations with me, again talking fairly 'normally'.

Most of the day now is spent on 1, 2, and 3 though obviously if friends and family are around a lot, there tends to be less of those conversations.
