Hey Guys! I was just wondering if you would think talking to one's self is considered normal or do I have some sort of mental health issue?

I've been doing it as long as I can think of and I constantly do it all the time. When no one is home I talk to myself out loud and even answer the questions that I'm asking, pretending that someone else is actually there with me and is answering them. To some degree I believe that someone who I talk to is around me even though I know he doesn't exist.

So what do you guys think?
