The rock in your dream symbolizes strength, permanence, stability and integrity. The two-headed snake beneath it refers to cooperation and teamwork in some relationship. Being bitten by it symbolized hidden fears and worries that are threatening you. Being chased by it is a metaphor for some form of insecurity. Means you are avoiding a situation that you do not think is conquerable.
My interpretation is:
Behind your strength/stability is a relationship that requires more cooperation/teamwork, and you have your doubts and worries.
