Dreams can often be rich in symbolism and reflect various aspects of our waking lives, emotions, and relationships. Here’s an interpretation of the elements in your dream:

1. Camping with Family and Friends: This setting may symbolize a desire for connection and camaraderie. It suggests a sense of community and support from your loved ones, indicating that family ties and friendships are important to you.
2. Niece and the Ghost: Your niece represents innocence and the potential for growth. The fact that she saw a ghost, named Loley, might reflect your feelings of concern for her wellbeing or anxiety about the unknown aspects of life. Ghosts in dreams can symbolize unresolved issues or aspects of the past that may need attention. The interactions with Loley could indicate a need to confront or acknowledge these unresolved feelings.
3. The Necklace and Intentions: The necklace in your dream signifies intention and focus. It suggests that you may be contemplating where to direct your energy or priorities in life. The fact that it landed on Loley might indicate that you need to pay attention to your intuition or the spiritual aspects of your life.
4. Multiple Friends: Encountering many versions of your friend could suggest feelings of confusion or the complexity of relationships in your life. It may also indicate that you are seeking clarity regarding your friendships or how you perceive others.
5. The Pregnant Dog: This part of the dream might represent nurturing instincts and the creation of new ideas or projects. The overly affectionate dog administering an inhaler could symbolize external influences or advice that you may be receiving regarding something you are considering "giving birth" to in your life. The desire to end the pregnancy could reflect fears or concerns about taking on new responsibilities.

Overall, your dream seems to touch on themes of family, concern for loved ones, the need to confront the unknown, and the complexities of your relationships and responsibilities. It may be useful to consider any current situations in your life that align with these themes and reflect on how you can address them.
