What Does This Dream Mean?

What did you do before you when to bed? some times we will have nightmares after seeing something disturbing before you sleep even days before. And did you eat any sweets before going to bed? That will give you nightmares, and it's not uncommon for people to bruise them selves in their sleep. I have had some bad nightmares before and woke up bleeding from my wrist. Turns out I hit my hand on the table corner. If the dreams keep happening, and it is really bugging, you should see a therapist, before you see someone that will tell you to pry it away.
