""Getting stuck" is a psychic occurrence so often repeated during the course of human history that it has become the theme of many myths and fairytales. We are told of the Open sesame! to the locked door, or of some helpful animal who finds the hidden way. In other words, getting stuck is a typical event which in the course of time, has evoked typical reactions and compensations. We may therefore expect with some probability that something similar will appear in the reactions of the unconscious, as, for example, in dreams. In such cases, then, my attention is directed more particularly to dreams." - C.G. Jung - "The Aims of Psychotherapy"
