To see a spider in your dream indicates that you are feeling like an outsider in some situation. Or perhaps you want to keep your distance and stay away from an alluring and tempting situation. The spider is also symbolic of feminine power or an overbearing mother figure in your life. Alternatively, a spider refers to a powerful force protecting you against your self-destructive behavior. If you kill a spider in your dream, then it symbolizes misfortune and bad luck.
