In the first part of your dream, you are with one of your better students and you are both sniffing a musty blanket for knowledge. This may represent a desire to gain more knowledge or insights about your teaching methods, as well as a desire to help your student learn more effectively. The fact that the blanket is musty may suggest that there are aspects of your teaching style that may be outdated or in need of freshening up. Your student's tendency to give answers to the other students may also reflect a desire to take control and demonstrate mastery, rather than allowing others to discover knowledge for themselves.
Moving on to the second part of your dream, you find yourself in Massachusetts at a garbage dump. This may represent feelings of being overwhelmed or burdened by the negative aspects of your past, including your family's stance on your vaccination status. The fact that everything is in big plastic bags may suggest a need to contain or compartmentalize these negative experiences. The toxic glass may symbolize toxic relationships or negative emotions that you have been trying to avoid. The restaurant may represent a desire for nourishment or emotional fulfillment, but the fact that you don't eat there suggests a sense of hesitation or reluctance.
The third part of your dream takes you to China, where you are warned about being overcharged for shopping. This may represent a fear of being taken advantage of or not being able to navigate unfamiliar situations. However, your willingness to test the camera and your confidence in doing so may reflect a growing sense of empowerment and self-assurance. Your desire to move to China for a new job may represent a desire for growth and new experiences, but your skepticism towards the critical videos you watched may suggest a need to question your own assumptions and biases.
In my opinion, this dream may be reflecting a desire to gain more knowledge and improve your teaching methods, as well as a need to confront and overcome negative experiences from your past. It may also suggest a desire for growth and new experiences, but a need to approach these with caution and self-awareness.
