I also just came across this term a few days ago. At first I thought well this is me, but then I wondered why it's a problem? I think from what I read that it's only maladaptive if it's interfering with your life. And I really don't think it is for me. I'm getting better at being social instead of daydreaming, when I have to. If I couldn't day dream I wouldn't get through the day. About the writing, I have written some fan fiction about my favourite band, which was a good way to kind of live out my fantasies through writing, I always felt so good after writing one, though I haven't in a while now. Sometimes the world in my head is just more interesting than the real world!
