C.s. Lewis said this quote

“ [The fairy tale] is accused of giving children a false impression of the world they live in. But I think no literature that children could read gives them less of a false impression. I think what profess to be realistic stories for children are far more likely to deceive them. I never expected the real world to be like the fairy tales. I think that I did expect school to be like the school stories. The fantasies did not deceive me: the school stories did. All stories in which children have adventures and successes which are possible, in the sense that they do not break the laws of nature, but almost infinitely improbable, are in more danger than the fairy tales of raising false expectations… This distinction holds for adult reading too. The dangerous fantasy is always superficially realistic. The real victim of wishful reverie does not batten on the Odyssey, The Tempest, or The Worm Ouroboros: he (or she) prefers stories about millionaires, irresistible beauties, posh hotels, palm beaches and bedroom scenes—things that really might happen, that ought to happen, that would have happened if the reader had had a fair chance. For, as I say, there are two kinds of longing. The one is an askesis, a spiritual exercise, and the other is a disease. ”
