A girl can represent many different things. For clues to her meaning, consider the context of the girl, and your feelings about her.
If the girl is someone you know in real life, she may represent that actual person or the type of role she plays in your life (friend, girlfriend, daughter, etc.).
Whether you know the girl or not, she could represent:
- The key characteristics that stand out about her in the dream, such as humor, acceptance, femininity, intelligence, etc.
- General young female characteristics such as innocence, beauty, gentleness, purity, creativity, intuition, shyness, or playfulness
- Your inner child, your playfulness and need for fun, or your vulnerability and need for support and empathy
