When i'm alone i pretend i'm not and act out situations
When I'm on my own, I pretend that there is another person in the room with me, but it's never a conscious decision to imagine them. Then, I act out random situations, like what I would do if that specific (always made-up) person asked me a certain question or did something. Sometimes I think about what I would say to a doctor or my mother or something too. I would always answer the questions with actions, but I can never remember afterwards if I spoke out loud, whispered, or answered in my head. I only realized recently that I do this, but I know I've done it for a good few years now. I do it a lot when I'm in front of a mirror too. I'm getting worried about my mental health.
