Hello

I was wondering about conversations with myself. I do it a *lot* probably around 2 hours per day. I literally talk to myself, not like I remind myself to wash the dishes or brush my teeth but actual thirty minutes of monologue. I’d talk as if someone was listening. I’d talk as if I was talking about a past story, or as if I were sharing my introspection. It helped me a lot, I understood so many things about myself by allowing myself to do it more often. 
It’s basically the same thing as people who write their thoughts to externalize. Except, I’ve never heard of anyone talking to themselves. And from what I can see online, I can only find people who will complain, or remind themselves what they have to do etc…
Is it normal? Am I the only one doing this?
