Your point is well taken.   So many talented people express themselves through literature, music, and movie making that has a fantasy theme woven thought out, and the effects are astounding.   For example, The Lion, The Witch and the Wardrobe was so well written as a book, and then in the movie, all that had been imagined, suddenly had dimension and animation.  All the beauty and strangeness was captured on film, and the viewer is filled with every kind of emotion, and left with such peace and hopefulness.  Of course, there is a direct correlation between knowledge, and using it to enhance our fantasies.   Giving fantasy gifts to those we care about is just one more dimension of the experience.
