Black Eye 
Having a black eye in a dream symbolizes defeat in waking life. Your black eye points to a blow you've taken recently. Experiencing a dream in which someone else has a black eye, you may be feeling bad for this person in waking life.
Not knowing the person with a black eye in your dream symbolizes your subconscious mind suggesting you to be more sympathetic and less argumentative.

Queen of Hearts
To dream of the queen of hearts indicates either the opportunity to meet your mate and fall in love, or to renew a love that may have been flagging through unawareness and inattentiveness.
