Dreaming of running often symbolizes a desire to escape or avoid something in your waking life. The snake can represent various things, including fear, transformation, or hidden threats. Since you were behind the snake, it might indicate that you are aware of a situation or emotion that you feel is creeping up on you, but you are not yet ready to confront it.

This dream could suggest that you are trying to outrun your fears or anxieties. It may be a good idea to reflect on what in your life feels overwhelming or threatening and consider facing it rather than avoiding it. Additionally, the snake could symbolize a transformation or change that you might be resisting. Embracing these changes could lead to personal growth.

Consider journaling your thoughts and feelings about the situation in your waking life that may relate to this dream. This might help clarify what the snake represents for you.
