I have conversations with myself
I don't exactly talk to myself, but I have conversations with myself. I imagine myself having a conversation with someone and think of ways they would likely respond. I usually have these conversations with people I know (well, myself) but sometimes if I see someone that looks interesting I do it. If I don't know them I make a personality for them and it's sorta like getting to know a new person. I can sometimes become great friends (in my head) with a person that I've only seen the face of.
I don't say the words in the conversation out loud, but I move my mouth as I would if I were talking but have no sound come out, like lip syncing I guess. I only mouth the words if It's me talking and not the other person though.
Is this normal?
