Dear God, this explains a lot...
I created a whole world. A couple, actually. I'm fixated on one right now, one that repeats itself often. I think it's because I grew attached to those characters, those complex personalities I created. I did it all the time when I was younger, and I always believed it would fade away when I was older.
It never did, so now I just accept it and don't tell anyone. I hope to make many of the older stories books one day.
Actually, I'm now inspired to create a thread for people to share their MD experiences. I want to hear what people think about.
Do it. I'd like to hear the gist of your two worlds.
