I sort of do this as well. I definitely think I use it for escape. When I was younger it was all about a boy I liked would come to my window at night and profess his love for me in fairy tale fashion, I still do that sometimes but in a different way ;-) Mostly now, with the pressures of adult life, I dream of winning the lottery and I go step by step in my head how I would use the money to pay off debts to go to the salon buy new clothes, go to the doctor, and travel. My fantasies have always been about meeting some needs and relieving long term suffering. I can't really relate to almost detaching from reality because of these fantasies, that's never happened to me. BUT, I do use books and movies to stay out of my own.head and reality so much that I'm not living a normal functional life.
