Your dream is rich with symbolism and personal connections, offering a tapestry of emotions and themes. Here's an interpretation of some key elements:

1. Roommates and Shared Space: The introduction of roommates into your home, which you've lived in alone, suggests a desire for connection or change in your life. It may reflect feelings of loneliness or a need for community, especially as you mentioned a shift from wanting to keep people out in previous dreams. This could indicate a growing comfort with vulnerability and openness to others.
2. Partition Wall: The act of creating separate spaces with a partition wall may signify your need for personal boundaries. You might be trying to find a balance between intimacy and independence in your relationships.
3. Friends and Relationships: The presence of your friends, Oluchi and Patty, might represent aspects of your own personality or your feelings towards these relationships. Oluchi's irritation over cleanliness could symbolize underlying tensions or unresolved issues in your friendship with her. Offering to swap rooms indicates a desire to accommodate and support those you care about.
4. Past Pets and Healing: The vibrant and healthy presence of past pets, especially the reunion with your sister's lost bird, signifies healing and closure. It reflects your empathy towards your sister's grief and a hope for her recovery. This part of the dream suggests a nurturing aspect of yourself, focused on helping others find peace.
5. War and Protection: The idea of planning a war to protect humanity indicates a strong sense of purpose or responsibility. This could represent your desire to fight for causes you believe in or to protect those you love. The connection to the Egyptian god Hapi might symbolize fertility, abundance, and the nurturing aspects of nature. Perhaps it reflects a call to embrace your inner strength and leadership qualities.
6. Diversity and Identity: The fact that your roommates are all black while you identify as Ojibwe may highlight themes of unity in diversity and exploring different perspectives. This could suggest a journey of understanding and embracing various cultural identities, including your own.

Overall, your dream speaks to themes of connection, healing, boundaries, and the search for meaning in relationships and responsibilities. It might be beneficial to reflect on how these themes play out in your waking life and consider any changes you wish to make in your relationships or personal boundaries.
