HORRID dream, somebody help PLEASE?

I wouldn't worry about it. If it were a reoccurring dream then I could only speculate that, subconsciously, you are contemplating your mortality by metaphorically staving off death; only that death, though only wounded, is letting you know that it's there, it has control, and that at any moment of it's choosing it will do what it wants, when it wants (sometimes with a sick a sick sense of humor). Keep in mind that dreams are created and controlled by the mind and limited by its experiences and perceptions. Nobody is going to kill you and nothing bad is going to happen just because you had a bad dream... it just happens.
