Imagination is the ability to produce and simulate novel objects, peoples and ideas in the mind without any immediate input of the senses. It is also described as the forming of experiences in the mind, which can be re-creations of past experiences such as vivid memories with imagined changes, or they can be completely invented and possibly fantastic scenes. Imagination helps make knowledge applicable in solving problems and is fundamental to integrating experience and the learning process. A basic training for imagination is listening to storytelling (narrative), in which the exactness of the chosen words is the fundamental factor to "evoke worlds".
