Dreaming that you are covered in blood is a precursor to getting rich. You'd better pay attention to making a fortune when you're being hunted and covered in blood. But your bleeding during menstruation has psychological subconscious hints. It may be that the physiological period is coming, or it may be that normal physiological and endocrine changes have caused your sense of touch during sleep.
I hope you treat life healthily and life will repay you.
