This dream seems to reflect feelings of anxiety and a sense of loss of control, particularly regarding a significant relationship or situation involving Charlotte. Here are some interpretations of the various elements:

1. Boarding the Plane: This can symbolize embarking on a new journey or phase in life. The fact that Charlotte is the one boarding the plane may indicate that you are concerned about her choices or direction in life.
2. Missing Suitcase: The suitcase often represents one's identity, baggage, or past experiences. The fact that it is missing could suggest that there are unresolved issues or feelings that Charlotte, or perhaps you, are carrying but not fully addressing.
3. Automated Walkway and Train Station: These settings may symbolize transitions and a journey. The train station is a place of waiting and change, which might reflect your feelings about the current state of your relationship or situation.
4. Narrow Plane and Climbing Down the Ladder: This imagery can indicate feelings of being confined or restricted. The difficulty you experienced in navigating the plane could symbolize challenges in communicating your feelings or concerns.
5. Earthquake: The shaking suggests instability and fear. This could represent anxiety about the future or a situation that feels out of control.
6. Man Behind the Curtain: This figure may symbolize an external force or influence that is affecting your relationship or situation. His actions indicate feelings of helplessness or being trapped in a scenario you cannot control.

Overall, your dream seems to express a deep concern for Charlotte and perhaps a fear of losing her or not being able to protect her. It might be helpful to reflect on your current feelings regarding your relationship and any changes that may be occurring. Open communication with Charlotte could alleviate some of the anxiety you are experiencing.
