Nothing. It is just a dream, they don't mean anything. Don't worry. You're fine.
Another possibility:
The emphasis on "physically" suggests that the injury could be coming from within the dreamer's body. Dreams are directly effected by physical conditions, inflammation, hormonal imbalances and everything else within the physical body. This might be a nudge from the subconscious that the dreamer is due for a health checkup.
The actual meaning of the dream depends on what the person was doing in the dream and on your feelings during the dream. But it is possible that you may still be effected by the emotional consequences of the abuse and should get some professional care.
It means that you have latent or repressed anger toward them.
It means hurt in your mind and your body.

Protecting individuals from abuse means you protect someone from being physically abused, verbally abused, emotionally abused or sexually abused.

Every dream is about the person having the dream. So this dream of your double is about the person that dreamt that dream, not about you.
It means that you are a very passionate person, or that you would like to let some of your hidden passion out.
It means that you are nervous about your crush.
This dream only means that the person interests you. Your mind might be using the image of this person to represent something in your dream, such as an attractive, exciting person, or, contrarily, a scary, threatening person. In any case, your dream does not mean that the person was thinking or dreaming about you.
Dreams are about the person having the dream. So this other person's dream is about that person, not you.
Being teased, made fun of, humiliated, or in some cases even physically abused not in a drastic way but in a childish way.
It means you are in love with that person
that you like them
