From Some Time I Started Writing A Story In My

from some time i started writing a story in my head, ,more like a fantasy, the thing is i kept adding more and more to the story like seasons more characters, it kind of relaxes me or you can say gives me pleasure, the problem is i need to know is it healthy of me to imagine or think of such story as it has been now few years, mostly i write this story during free time, or before falling asleep i never wanted to write it down, neither i have ever told about it to anyone
