In your dreams, selling glass indicates that you might suffer from financial losses in the future. You may enter a job or take up something you don't want to to make ends meet.
You will have a difficult time, but you will be required to make quick decisions for a better future, despite personal disparity and issues. People will offer help to you only when you grow out of this situation and mature.
This will force you to only rely on yourself in difficult situations. So it is important to keep working hard individually towards your own goal.
