I am SO glad I found this post!! Thank you so much for posting about this. I'm sorry I can't help you out with solving the problem as I too do exactly the same thing and didn't think it happened to people in general and it is very difficult to explain like you say. I'm glad I'm not alone with this but I'm sorry it happens to you too cos it is really difficult when it happens and sometimes it can be important stuff too which you could really do with hearing and comprehending. I always forget to ask my T about this but like jadedbutterfly says it makes sense that it is dissociation I suffer with that anyways so suffering with that within conversations must be pretty normal to people like us. I hope to find ways to stop this happening to me too. I understand exactly what you mean and it's really hard to struggle with!
