If in your dream you see yourself being hurt, this is usually a pure reflection of a real life situation - you may experience suffering and grief in the waking life due to people who have hurt you, which causes the subconscious to accumulate negative emotions and bring them up in dreams. Consequently, emotional pain in a dream is closely connected to the sorrow you experience in the waking life - to escape such dreams which only make your soul bitterer, you should find a way to deal with past events, to forgive and forget, in order to be able to move on and achieve a general balance and equilibrium in your life.
On the other hand, if you hurt an individual, this may stand for some of your negative traits of character, such as being self-centered and ignorant when it comes to the feelings and needs of others. To hurt and cause pain to someone you know in a dream may also be a bad omen which foretells bad luck and unfortunate events to follow in your life.
