Dream of snakes
Even people who haven't read the Bible know that Eve and Adam were expelled from the Garden of Eden because they listened to the rumors of snakes and began a miserable life on earth. In many primitive cultures, snakes look unfathomable, which makes people feel inexplicably awed and even regarded as gods. Snakes therefore symbolize the desire to stir in human nature, unfathomable power, and awe at the same time.
Most people dream that snakes are unpleasant experiences, perhaps being chased and swallowed by snakes; Maybe it's just dormant and doesn't hurt you, but you just want to run away in fear! When you dream about snakes, especially when you feel extremely scared, it probably means that you have met your own deep fear. Think about what kind of snake you dream about. How do you feel about the snake in your dream? How do you interact with it? Where did you meet this snake? All these can help you to know more about what you are afraid of.
Dreaming of shrimps and crabs means that you will get rid of the difficulties in life immediately.
In a word, this should be a good dream for you. It's nothing. The most important thing is to believe in science. Don't worry!
