You project your emotions on the cat.
The broken tail symbolizes a physical and mental blow and makes you feel lost.
Very surprised, touching its body, my heart hurts.
This reflects that you observe your inner state, feel that you are in a bad state and feel sorry for yourself.
Tail represents personal image. In addition, although it is not very important, it is also a necessary part. Breaking it means it has been damaged.
It grew out again the next day, which means a state adjustment. Although you have been injured before, you will return to your original good state after thinking and rest.
Without warning, dreams only reflect changes in thoughts.
