Trapped in My Own Head

I talk to myself. A lot. Like full on conversations with the invisible "me" in the room. Sometimes just in my head, but sometimes the conversation is out loud. Yes, I respond to myself. Sometimes it is like I'm arguing with myself and at other times it's almost as though I'm my own therapist. I don't think this is healthy, but I can't remember a time when I didn't do this.
Also, there are times when I pretend I'm talking to a different person. Not me, but not a real person either. Like I'm trying on a conversation to see how it would play out with a specific kind of person. Usually the train of thought strays and I just go back to talking to myself, but still. I make up people to talk to.
I don't think this is normal.
Should I talk to a professional, or just continue talking to myself?
I like myself better than a stranger, so I'll probably just stick the the latter.

:Poetic moment:
I look into your eyes and fall into the depths of your soul. I want to drown in you.
Envelope me in all that you are and make us one.
I am drawn to you. In the most powerful way possible.
Like a magnet - I just can't resist the pull.

:Quote:
Sometimes the hardest thing to let go of is
Something you never really had; what could've
Happened didn't. It's jut they way the cookie
Crumbles. This is my goodbye to you.
I'll never forget the way you made me smile.
