Dreams often weave together elements from our waking life, emotions, and subconscious thoughts. Let's break down the significant elements of your dream:

1. Meeting Papa from "Ghost": This could symbolize a desire for connection or a longing for guidance. The act of hugging or taking a photo may represent a wish to capture moments or memories, indicating the importance of familial or supportive relationships in your life.
2. Airport Anxiety: Airports often symbolize transitions or journeys. Your fear about not having the right ticket may reflect feelings of uncertainty or anxiety about a new phase in your life. The assistance from the lady behind you suggests that help is available, and you don't have to navigate your challenges alone.
3. Camp Simulator and "Handmaid’s Tale": This part of the dream could signify feelings of being in a controlled environment or having to follow strict rules. The fear of being listened to while on the bus may indicate concerns about privacy or judgment in your life. It could reflect how you feel about expressing yourself or your interests.
4. Bathroom Scene: Bathrooms often symbolize a place of cleansing or transformation. The clutter suggests that you may feel overwhelmed or unprepared in some aspect of your life. Rushing to meet Papa indicates an urgency to connect with something meaningful before it feels too late.
5. Family Presence: The appearance of your dad and siblings represents support and connection to your roots. Walking together suggests a shared journey and that you are not alone in your experiences.

Overall, your dream seems to reflect themes of connection, support from loved ones, anxiety about transitions, and the desire for clarity in your life. It might be helpful to consider what "Papa" represents to you personally and how these themes resonate with your current feelings or situations. Embrace the support you have around you, and try to address any anxieties by seeking clarity in your waking life.
