What does it mean to dream about the devil?

In dreams, the devil is a metaphor representing evil. The subconscious mind uses the image of the devil to symbolize the dreamer's fear or the sense of imminent harm. The concept of a powerful, malicious being who actively seeks to harm or seduce innocent people has roots in past ages when there was no other way to explain natural disasters, Infectious Diseases, mental illness and countless other "evils."

> The devil might also represent the dreamer's own sense of guilt. By "projecting" the sense of evil onto the mythical personification of evil, the dreamer is relieved of the uncomfortable sense of being responsible for wrong-doing: the sin is located in the image of the devil rather than in the self.
