imagery

n. visual images, pictorial representations; imaginary images, images created in the mind

Imagery is any of the five senses(sight, touch, smell, hearing, and taste). Essentially, imagery is any series of words that create a picture in your head. Such images can be created by using figures of speech such as similes, metaphors, personification, and assonance. Imagery helps the reader picture what is going on.
