Dreaming of being a passenger in a large plane can symbolize a sense of being on a journey or experiencing a transition in your life. Here are a few interpretations to consider:

1. Lack of Control: As a passenger, you may feel a lack of control over your direction or destination, which could reflect feelings of uncertainty or being carried along by circumstances in your waking life.
2. Trust in the Journey: Being on a plane can also signify trust in the process of life. It may suggest that you are relying on others or external forces to guide you through a phase of your life.
3. New Experiences: Air travel often represents new opportunities and experiences. This dream may indicate that you are open to exploring new possibilities and adventures.
4. Perspective: Being high in the sky can provide a different perspective on your life. It may encourage you to look at situations from a broader viewpoint or to rise above challenges.
5. Escape: If the plane journey feels more like an escape, it could indicate a desire to break free from routine or current problems.

Reflect on your feelings during the dream and any significant events happening in your life to gain deeper insights into its meaning for you.
