I often dream about disgusting things, corpses, maggots and snakes. Please master the advice!

This is called anxiety dream in psychology. Dream is a way of thinking, but it is a subconscious way of thinking. Because the consciousness is weak and the subconscious is dominant during sleep, the dream lacks logic, and its content comes from real life scenes, which is disordered after processing, transformation and splicing. For example, your dreams may come from movies or recent events. Don't be afraid, dreams don't mean foreshadowing or omen. It can only be said that it is an internal latent thinking, which is vague enough to subconsciously create a scene: this dream may be the reality of your long-term anxiety, and may be caused by some pressure in real life.
