A dream about evil is probably a message from your dreaming mind that something is not right in real life.
Dreaming that someone or something is evil, or that you are surrounded by an evil force, does not mean that someone or something in your life is truly “evil”, in a moral or religious sense. However, someone may be behaving inappropriately, perhaps being selfish or deceitful. They may even have simply made a bad choice about something.
In fact, the “evil” person in your dream could be you – you could be worried that you have made a mistake about something or you could be feeling guilty about something that you have done.
Being in an evil place in a dream can be a sign that you are in a dangerous situation in real life.
Evil in a dream can symbolize repressed emotions or thoughts. If you experience a sense of dread in your dream, it could mean that you are worried about having to face these repressed thoughts or feelings.
