Snake is one of the common animals in dreams and one of the most commonly used images. Snakes are rich in content. First of all, snakes in dreams are sometimes symbolic. In women's dreams, snakes symbolize male genitalia, and their shapes are indeed similar, while poisonous snakes symbolize sexual harm. Attitudes towards snakes in dreams, such as love, disgust and fear, can often explain the dreamer's attitude towards sex. Common dreams include being chased, entangled and bitten by snakes. Escape and chase symbolize the dreamer's fear of sex. Being haunted by snakes symbolizes the love between men and women; If women often dream of being bitten by snakes, it means that the dreamer has anxiety about being invaded by the opposite sex. Secondly, in physiology, snakes also represent the spine, and the lesions of the spine will be represented by injured snakes. From the perspective of yin and yang, snake means yin. Thirdly, snakes also represent evil, cunning, cold-blooded, deception and temptation, which is the same as the image of snakes in many myths and folklore. In the Bible, it was the snake that lured Eve to eat the forbidden fruit. Snakes are often regarded as animals in hell or messengers of the devil. They drag people to darkness, depravity and evil, and the main means it uses is temptation. According to folklore, snakes don't take the initiative to catch frogs. Once they find frogs, they stare at them with their eyes. At this time, the frog will jump into the snake's mouth step by step as if he were hypnotized. In people's minds, snakes represent such a hypnotic temptation. So when people find a person attractive and evil, they call it a poisonous snake; If the seducer is a woman, we will call her a beautiful snake, a femme fatale or a poisonous snake. Therefore, the snake in the dream may be an evil, cunning, deceitful and hypnotic person.
