Dreaming of earthworms, good luck, indicates that there will be gains in work and life.
Dreaming that earthworms lengthen their bodies indicates that they will benefit from real estate. (Congratulations)
According to science:
Dream is a subjective experience, an imaginary image, sound, thinking or feeling produced by people during sleep, which is usually involuntary. The causes of dreams are inextricably linked with people's social environment, psychological factors and physical condition. (that is to say, there is no difference between good and bad)
According to my idea:
My nightmare is usually because I am tired recently, I am in a bad mood, or I have encountered some difficulties in my life and work. Pay attention to rest and adjust your mood. My own experience may not apply to everyone, but I hope it can help you.
