That's kind of similar to the kind I used to have. I had two, one on each side of me--one was mainly good and we would chat...though she could get as nasty as the other one was all the time. They kept up a running commentary about things going on around me as well as about what I was thinking. Sometimes they didn't speak intelligibly--but scream or make repetative noises for hours. I don't know if that is very similar to yours?
