However, creative visualization is closely related to, and is often considered as one part of, guided imagery. In guided imagery, a trained practitioner or teacher helps a participant or patient to evoke and generate mental images[27] that simulate or re-create the sensory perception[28] of sights,[29][30] sounds,[31] tastes,[32] smells,[33] movements,[34] and touch,[35] as well as imaginative or mental content that the participating subject experiences as defying conventional sensory categories.[36]
