Duke Zhou, my mother and I dreamed that my grandmother who was still alive died at the same time. How to interpret dreams?

Dreams are a reflection of psychology and sometimes have a predictive effect. According to your short sentence, I will make an analysis for the time being, and there are the following possibilities:

1, afraid of worrying about grandma's death.

Although the consciousness doesn't want to admit it, the subconscious wants grandma to die.

Grandma may not represent her, but someone similar to her.

Grandma's death indicates that some rigid aspects of your life, feelings or your heart will be removed and there will be a new beginning. Or you and mom want it.

Maybe dreams are facts.
