I talk to myself all the time. Sometimes I don't even notice it, it's become a part of me. Just thinking is not enough, you have to let it out. It sometimes scares me when I notice I've just been sitting on my bed talking to my self for half an hour. I start thinking I'm nuts. Usually I imagine someone sitting across me, either someone I know or a stranger. Then I have a conversation with that person. It's like therapy, it's easy to imagine as a therapy session. I imagine the person asking me questions and commenting on what I tell him/her. I wish I had a real therapist though...
