Dream about running blood suggests your raw emotions. You need to leave some aspect of your life to fate. You are struggling with your identity. It represents your fleeting desires of being wild, free and spontaneous. You are wasting your time and energy on frivolous pursuits.
Running blood dream is a hint for completion and wholeness. You are highly connected to your intuitive senses and psychic power. Perhaps you think that someone is trying to keep something from you. It suggests some sort of entitlement. You need to look at some problem or something from a new perspective.
If you dreamt about running blood:
Make sure you have love for the work you are doing. If your work is not inspired by a true love from within, then quit your job and find something else. Follow your passion. Follow your heart, and the money and opportunities will follow naturally.
