My daughter lost her daughter in a dream at night during the exam. Did she fail the exam?

That's because you have high expectations for your daughter. If you expect too much, you are afraid of losing. This fear has penetrated into the subconscious. Psychoanalyst Freud believes that dreams are the embodiment of the subconscious mind. So you will have such a dream, and your mood will be revealed from your daily words and deeds.

Dreams and Subconsciousness: Psychoanalyst Freud pointed out in The Analysis of Dreams that when people's conscious dreams are basically at rest, they only provide an outlet for the subconscious, and we can explore people's psychological motives and find opportunities for psychological anatomy through the analysis of dreams. As a basis for diagnosis and treatment of mental illness. However, when dreams and subconsciousness are considered on the scientific scale, unfortunately, there is no valid evidence for the inevitable connection between them.
