Thank you for your replies. I only dissociate during therapy normally when I'm trying to talk about something difficult but sometimes it happens and I don't know why. I can't tell when it happens it's like a switch that goes from being in the room talking to a dark fuzziness not feeling or hearing anything but a safe feeling. It's hard to describe but she just lets me continue to talk. I've read you shouldn't be dissociated when processing trauma so wondered why she doesn't stop it
