The Hypnagogic State. While studying the different types of altered states, I came across the subject of hypnagogic imagery. This type of image construction is not the self-deliberate creation of images one performs when one is daydreaming or visualizing. Rather, it is a spontaneous and non-controlled projection of images from the subconscious mind. These images are seen in the mind’s eye or imagination.
