Dreams about friends visiting can often symbolize your feelings about your relationships and social connections. In your dream, your friend picking up their belongings and leaving quickly might indicate feelings of abandonment or fear of losing touch with someone important in your life. It could also represent a sense of urgency or a need to resolve unfinished business in a relationship.

The airplane aspect of your dream suggests a journey or transition, often related to personal growth or change. Feeling trapped on the plane might reflect feelings of being stuck in a situation or unable to move forward in some area of your life. You may feel like you are unable to express your feelings or say goodbye properly, which can be tied to unresolved emotions or situations.

Overall, this dream could be prompting you to reflect on your relationships and how you navigate changes or separations. Consider reaching out to friends or loved ones to strengthen those connections, and think about any situations in your life where you might feel trapped or in need of closure.
