Introduction
With the improvement of social, economic and cultural level, dance has gradually developed into an indispensable part of people's daily entertainment. Different types of dances can be seen in many places, which greatly enrich people's lives. Dance is an artistic form that people show through body movements. Some contents that are difficult to express in words can be presented through dancing. At present, with the continuous improvement of living standards, people's material needs are met. At the same time, people's pursuit of spiritual level is constantly improving [1][2][3] . As a result, the status of dance in society has been constantly promoted, and professionals in this field have also been accordingly valued by the public. Dance industry is in the stage of prosperity and development. Dance is a pursuit of art in people's life, so it has the characteristics of universality and popularity [4][5][6] . At the same time, dance is also the public's pursuit of beauty, through the extraction and beautification of body movements. Dance art can express things that words and language can not express, which makes people's feelings and thoughts more specific and vivid release. Dance art has greatly enriched the spiritual world of the public, which is also a manifestation of the status of dance in society. The concreteness of dance art imagination is mainly as follows. Dance content is realized and expressed by human body movements. During the creation and arrangement of dance, in order to ensure that the artistic image of dance is more distinct, it is necessary to incorporate representative and life-compatible movements. Therefore, higher requirements are put forward for the image thinking and observation of the choreographer. At the same time, dance has the characteristics of action, shape and intuition, which also puts forward the requirements for the concreteness of dance art imagination. In the creation of dance, we must select specific perceptual form from the imagination of dance art. Dance art imagination will highlight more specific and individual perceptual characters. Imagination helps dance artists create new dance works, which form more concrete and vivid pictures in their hearts.

Emotional imagination of dance art
Dance art imagination focuses on the emotions expressed. For dance artists, rich emotions play a vital role in their psychological life. At the same time, in the creative activities of dance artists, emotional imagination has great significance. Driven by rich emotions, the artistic image created by dance artists will be more emotional. As an excellent dancing artist, we should not only experience the emotions of different people through imagination, but also realize the emotional exchange of creating dancing artistic images in imagination. Only in this way can dance artists create better dance works. By experiencing the complex emotions of joy, joy, sorrow and sadness in artistic images, dance artists can achieve emotional resonance. Only in this way can dance artists create a more appealing image of dance art.

The fiction of dance art imagination
In scientific imagination, every value hypothesis put forward must be based on facts. Facts are the root of scientists'creation, so fiction is not allowed in scientific imagination. But compared with scientific imagination, dance art is quite different. In dance creation, the imagination of dance artists is often closely related to fiction. The authenticity of dance works is not necessarily a real case in real life, but a possible case, which is the product of artistic imagination combined with the logic of life. Dance works are reasonable fiction of artistic images, not arbitrary forgery of ideas.

Humorous and exaggerated presentation of artistic imagination
Through humorous expressions, dance works exaggerate and deform life. This kind of dance works are designed to talk about harmonious image and unexpected plot, the purpose is to achieve the artistic realm of "inhabiting zhuang in harmony". Among them, "Zhuang" is a profound social content, and "harmony" is the restoring harmony of the expression form. Through witty actions and exaggerated shapes, the dance "Silent Sunset" vividly presents the fractured texture and changes of the actors'joints. Through a lively and beautiful image, the audience can associate with the characters in the shadow play. Actors sometimes take off and jump, and sometimes turn their shoulders. It shows the hard, exaggerated and well-coordinated actions of the shadow play. Through the imagination of movement and shape, the dance works are humorous and full of vitality. Through a new form to show the audience the happy life of the elderly in their old age, the idea of "the most beautiful but sunset red" in the dance works enriches the connotation of the works. The shape of the dance Silent Sunset is shown in Figure 1.
The dance Pastoral Music is based on the image of the Scarecrow. The director endows the Scarecrow with emotion and personality through artistic imagination. In the aspect of action arrangement, the director vividly grasps the artificial and dynamic characteristics of straw, through exaggerated actions, such as fast up and down shrug, crotch flicker, hand and foot swing, etc. The expression of harmony shows the freedom and ease in the garden, and also leads to the beauty of harmony between man and nature. The shape of the dance Pastoral Music is shown in Figure 2.

Artistic imagination presentation of freehand brushwork
Freehand dance works mainly create an artistic conception. The imaginary works of freehand dance art are like a folded poem. By slowly unfolding a vivid picture scroll, whether it is the description of abstract things, or the description of scenery, we can not do without the exertion of artistic imagination. Through the situation conveyed by the works, the appreciator touches the scene, touches the feelings. This psychological process needs not only the artistic imagination of the creator, but also the second imagination of the dancer.
For example, the Danqing Fan Dance. By borrowing the folding fan which lengthens the expressive force of the arm, the classical dance is integrated with Chinese calligraphy culture, fan culture and sword culture. By combining dance, music, books and paintings, the dance works create an ancient, elegant and dignified image of traditional dance culture. In order to achieve the harmony between man and nature, the work deduces the charm of calligraphy art in a one-stroke performance. This artistic realm with endless words and meanings creates a tranquil, elegant and lofty artistic conception. The shape of the dance Danqing Fan Dance is shown in Figure 3.

Personalized presentation of artistic imagination
Personalized dance works mostly take natural objects (i.e. animals and plants) as the main body of creation, expressing the creator's thoughts and feelings through natural objects. The ancients fully understood the variety of nature and the rhythm of life. At the same time, it endows people with life characteristics, psychological characteristics and even moral characteristics. Writers personify natural objects in dance artistic imagination, so that nature has the emotional quality of human beings. On the contrary, writers comment on people's personality, character and temperament through nature as a reference. In the dance "Two Trees", trees with interdependent branches endow people with thoughts and feelings. Dance is a metaphor for the love between two men and women in love. Through artistic imagination, this paper achieves the effect of using trees to describe people and using objects to express feelings. At the same time, dance vomits the greatness of natural love. The shape of the dance "Two Trees" is shown in Figure 4.
