Anybody else?

So, I act scenes out between my characters in my head. When I do, I often voice out the words that the character(s) would or should say. I also get really into them and feel what my characters are feeling and occasionally act the scene out.

Sometimes, I don't even realize I'm doing it. It just happens. And sometimes I get loud enough that other people around me can hear.

The first time I realized this was when my sister asked what I was always thinking about. I looked at her like she was a fool, and asked her what the hell she was talking about. That's when she told me I'd be walking around the house with these strange looks on my face, sometimes like I'm going to cry. And that she heard me talking to myself.

Since then I try not to think about my characters until I'm in the privacy of my own room. So I don't look like a total weirdo or something.
