Your dream seems to encompass various themes, including feelings of being overwhelmed, nostalgia, and family expectations. Here’s a breakdown of some key elements:

1. Overwhelm and Harassment: The experience of being stopped by multiple men who were flirting but made you feel harassed could symbolize feelings of being pressured or overwhelmed in your waking life. It might reflect anxiety about social situations or expectations from others, especially regarding relationships.
2. Jackson Galaxy Reference: Bringing in a public figure like Jackson Galaxy, known for his work with cats, could signify a desire for guidance or support in navigating your current situation. His presence might represent the need for someone to advocate for you or assist you in managing overwhelming circumstances.
3. Nostalgia and Family Dynamics: The transition to the trail behind the old folks' apartments signals a journey back to your past, highlighting a connection to childhood memories and experiences. Being surrounded by family, especially your biological half-sister and mother, may suggest a longing for familial connection and comfort amidst your anxieties.
4. Settling Down Pressure: The presence of big guys wanting to court you and the underlying expectation to "settle down" could reflect societal or familial pressures regarding relationships. This part of your dream may indicate a fear of not meeting those expectations or a desire for independence.
5. Moving Out Memory: The intense memory of moving out of the Trailwood house, combined with the imagery of leaving food and water for pets, suggests themes of caretaking and responsibility. The nicer backyard with a garden and fountain could symbolize personal growth and healing since leaving that home, indicating that you are nurturing parts of yourself that were perhaps neglected in the past.

Overall, this dream might be urging you to reflect on your current feelings regarding relationships, family expectations, and your own desires. Consider what aspects of your past you wish to revisit or integrate into your present and how you can assert your own needs and desires amidst external pressures. Taking time to explore these feelings might provide clarity and help alleviate any anxiety you're experiencing.
