Therapeutic metaphor is a type of conceptual metaphor presented as a story or other parallel to an entire aspect of a situation, related by a psychotherapist to a patient. The purpose of this is to highlight to a person, in an effective way, some aspects and lessons that otherwise they might not be able to perceive as clearly in their current situation, or to suggest new outlooks on it. Thus a therapist, told about the untimely death of a loved one, might respond by describing two roses in a garden, one of which is dug up. (Wikipedia)
