What does it mean when you dreamed someone shot your daughter?

This could be an exaggerated expression of natural parental concern for your child's safety and welfare. Recent news reports of kidnappings, particularly of girls, might easily heighten your anxiety and trigger such a dream. Alternatively, the dream might express feeling of loosing control of your daughter, particularly if you feel that some other person or authority (such as a school or peer group) is having too much influence over your child.
