What is mental or guided imagery?
Imagery is the mind thinking visually in pictures. There are many ways we can think. For example, we think logically with words and non–logically through image, intuition, etc. We think in images all the time, but may not be aware of it. For instance, when we choose a shirt we are already envisioning ourselves in it before we put it on. A basketball player envisions the shoot before s/he shoots the ball. In fact, images form the structure of our inner life. For example, night dreams come in the form of images.
