The devil in dreams is the symbol of bad features that are lurking in your personality. The dream could also represent the regrets you have about something you did in the past. Perhaps the dream suggests letting go these feelings of regret. On the other hand, the devil may indicate the wisdom, smartness and resourcefulness. If you were fighting the devil in a dream, then it shows the success while dealing with your components. You will be the winner. If you had some kind of conversation with a devil, then it means you will have some temptation and will find it hard to resist. If the devil was pretending someone else and you got sued in some deal, then it shows the unknown badness you will be taken into by not your will.
