The inspiration from "subconscious mind", i.e. the subconsciousness of the brain, is critical to dance creation. This paper makes a thorough review of the theory of brain subconsciousness, details the elements of dance creation, and then determines the role and mechanism of subconsciousness in inspiring dance creation. The results show that, the inspiration in dance creation is a unity of functions, concepts and aesthetics achieved through long-term pondering, rather than appear out of nowhere; the generation and development of inspiration can be divided into three processes: preparation, excitation process, and capture and processing; the dance creation is an integration of logical thinking and nonlogical thinking: analyzing the bionic elements through logical thinking, converting them into inspiration fragment through nonlogical thinking, and integrating the fragments through logical thinking again. The research findings shed theoretical new lights on the study of brain neuroscience in dance creation.
