In this dream, the relationship between you and your mother and the harm your mother has suffered tell you one thing: you care about your mother very much, so you are afraid to hurt him for your own reasons. In fact, it can be said that your subconscious has told you that "it" will still wait for your mother. In daily life, the power of the subconscious can not be ignored, and uncontrollable impulse is one of the functions of the subconscious. Therefore, under such subconscious action, your relationship with your mother will only get better and better. In fact, this also coincides with the explanation that we quarreled with our relatives and committed suicide during the Duke of Zhou in China.
I hope these can help you.
