I dreamed that a big black dog was playing games with me. I threw the ball out and it helped me get it back. But before long, it died. I held it and began to cry.

A big black dog probably represents fatigue. Throwing and picking up the ball repeatedly means that the work is boring, or it is a reflection of your body's running rhythm. You feel tired. Crying too much is pity for yourself. You really should take good care of yourself, rest is the first priority, otherwise the problem may be serious. In fact, it is better to adjust your mind than to adjust your body. You can find a psychological doctor to relieve the pressure first, otherwise people will not let go easily in the Jianghu, and they will slow down and take it back if they want to get through it.
