What is it about Fantasy?

I have often wondered why I am so in love with the unreal. Why is it that I constantly cahse after things which I know are simply fiction? For example, take anime, or fantasy novels. What is it about the complete unrealism about them that enraptures me? Is it the abstract themes of mature thoughts presented in a way which is no longer burdened with the details and minutiae of real life? Do I love it as an escape? Why? If it is an escape, what would bring me to chase after an escape? What is it about this world with which I am disatisfied? Even so...how is it that it is the inhuman, the other worldly, to which I seem to so desparately cling? What is it about entering a realm of imagination, power, and freedom that grips me so securely? What is wrong with my head???
