When you dream vampire means: As a warning sign of psychic vampires (people around you who are emotionally draining), bat-like vampires can be seen. Strangely, women are more likely to fall for vampires because of the romanticized portrayal of them in Hollywood. If you kill a vampire in dreams, it’s a good sign. It means that your bad habits or behavior will be removed. It is a sign that you avoid dangerous people and aspects of yourself.
