You said that you dreamed that you didn't wear shoes, which means that you are worried about the operation, don't know whether to move forward, and feel confused and annoyed.
The foot is an important organ of the human body, with the most acupoints, and it is the first to know whether it is hot or cold. Your hands and feet feel cold, which is a sign of a heavy heart.
But then your mother helped you find shoes, which means you were just worried, and the result was good.
Take good care of your mother. Everything will be fine. Good luck!
