In my head.

In my head there is a world. Filled with creatures. I draw them, and sometimes color them. Is it wrong that  creatures are in my head? When I draw them I give them stories. I mostly draw wolves, but I also draw Anime people. Well I call them people, but I think they might be demons. They were created to become demons. If they had a choice trust me they wouldn't be demons. Well anyway do you think it's wrong?,  that there is characters in my head?, that are not real...
                 Is it wrong?
