A vampire is a fictional creature from folklore and horror stories that supposedly rises from the dead at night to drink the blood of living people. According to legend, vampires sleep in coffins during the day and come out after dark, using sharp fangs to bite their victims' necks. Traditional stories say vampires fear sunlight, garlic, and crosses, and can only be killed by driving a wooden stake through their hearts.

The vampire legend originated centuries ago in Eastern European folklore, when people tried to explain mysterious deaths and diseases they didn't understand. These stories spread across the world and evolved into countless books, movies, and TV shows. Famous vampire characters include Count Dracula from Bram Stoker's 1897 novel, which remains one of the most influential horror stories ever written.

Today, vampires appear in stories ranging from scary to silly, from terrifying monsters to misunderstood heroes. Some modern versions even sparkle in sunlight or attend high school. Whether portrayed as evil villains or complex characters struggling with their nature, vampires remain popular because they explore fascinating questions about immortality, power, and what it means to be human.

The word can also describe someone who drains others emotionally or takes advantage of people, like calling someone an energy vampire if they constantly demand attention and leave everyone feeling exhausted.
