The word 'vampire' appeared in the English-speaking world in the 1730s

However, earlier mentions of creatures with similar characteristics existed throughout Medieval Europe. For example, people often spoke of revenants—restless dead creatures who tormented the living.

These older revenant stories eventually influenced modern vampire folklore.

The ‘Universal Monsters’ series solidified horror as a film genre

Before 1931, most scary movies were billed as “mystery” or “suspense” with grounded explanations for anything "supernatural."

Universal continued adapting similar titles, including HG Wells’ “The Invisible Man” and Edgar Allan Poe’s short stories.

One doctor argued vampires were based on a real disease

At a conference in 1985, Canadian biochemist David H. Dolphin posited that stories of vampires and werewolves had a real-world origin.

Early English fantasy writers built on horror and Gothic texts

After the success of 19th-century books like Mary Shelley’s “Frankenstein” and Robert Louis Stevenson’s “The Strange Case of Dr. Jekyll and Mr. Hyde,” readers were eager for more stories that deviated from realism.

Dickens' pet inspired Edgar Allan Poe's 'The Raven'

Dickens had a pet raven named Grip and made him a character in the novel "Barnaby Rudge: a Tale of the Riots of Eighty." Poe reviewed the work and suggested the raven should play a bigger role. A few years later, he fixed the problem himself when he wrote his most famous poem, "The Raven." The bird is preserved at the Free Library Philadelphia.

Before he was a famous novelist, John Steinbeck wrote a werewolf murder mystery.

Cordyceps: the fungi that turn ants into zombies

The hit show (and video game) "Last of Us" was inspired partly by real-life species of fungi that have been known to turn ants into zombies.

The fungal cells then hack the ant's nervous system and trigger compulsive climbing.
