Dreaming will not affect people's rest, but after being awakened in the dreaming stage, people will feel uncomfortable feelings such as general weakness and listlessness. All kinds of dream studies have given positive answers, even though 90% of dreams are forgotten by us. These things that can't be actively remembered have become an important part of our subconscious. Better behavior patterns can be strengthened in dreams, and those terrible threats may also help us avoid similar dangers during the day.
The subconscious mind contained in dreams will convey information through pictures. For example, I dream that I am naked in public: clothes are a protective layer, which is a symbol of identity. Naked represents insecurity, afraid of being seen through weaknesses, and I try to hide it, afraid of revealing my privacy. Being in a tall building or cliff, you are afraid of falling: people around you have high expectations of you, but you work hard but are worried about disappointing others.
Looking for a toilet, the toilet sanitation is very poor, and the ground is full of feces: it means suppressing one's own needs and desires, having negative cognition about it, and restraining oneself. In fact, dreaming actually reflects the problems inside and outside the body during sleep, and it is also very simple. For example, you will be awakened by the temperature drop in the room, or you will be directly awakened to go to the toilet because of urgency, which means that dreaming is caused by internal and external stimuli of the body, so dreams are unpredictable. Many dreams are caused by the pressure of work during the day. Dreams can't predict anything, but people who often dream should pay attention to their sleep quality.
