Mine is quite separate, I sometimes feel like I have two brains. It feels like a dialogue, but it's happening in your own head. The child brain usually wants to do childish things, like buy toys, sometimes it is scared of stupidest thing you could imagine. I didn't have to discover it, it was always there, it's more like one part of me grew up, but the other one didn't. It knows when it's ok to pop up and when it's not, so I have no trouble about it and hence I don't do much about it. I guess I just learned to live with it so long ago that I don't notice it. It's who I am, and if I want to buy a lollipop and watch cartoons, well, it's my life and I can do whatever I want, don't I And if the child part is scared of something (i.e. going to the doctor), the other part promises that it will take care of everything and the child part can go hide safely until it's over. It's more or less a happy family with strictly divided jobs
