Fairy tales are by no means merely imaginative stories, if one follows the views of developmental psychologists. It turns out that various developmental phases and maturation processes that the adolescents in fairy tales have to go through are not very different from adolescence processes of real adolescents. Fairy tale characters have to overcome numerous trials and tests in order to be considered a grown man or a real woman at the end. It is made clear that every person, whether real or fictional, has to overcome various hurdles in order to become an adult, which differ from each other only in the way they are carried out. Thus, one leaves home to get to know himself and the world better, but the other has to be literally pushed out of her mother's nest to find happiness.These processes of adolescence can not only be transferred to numerous fairy tales by the Brothers Grimm, but are also found in the world of real adolescents on their way to the kingship of life, to maturity.
