Imaginary Friends in Horror Novels that Evoke Real Terror

Nothing is quite as scary as the imagination.

four horror book covers about imaginary friends

Maybe when you were younger, while your parents were too busy to play and you found yourself immensely bored, you created your own companion to keep you company: an imaginary friend. Someone who would always give you an enthusiastic “Yes!” to every single one of your whims and would make the hours of the day more fun and far less lonely.  

According to research, around 65 percent of kids up to age seven have created an imaginary friend and experience benefits from this type of play, including increased creativity, emotional understanding and sociability. 

But what if an imaginary friend starts acting cruel? What if suddenly your child’s invisible buddy is telling them to hurt others or themselves? How can you prevent harm from an entity that isn’t supposed to be real? 

These are the kinds of questions examined in horror novels that morph this innocent childhood phenomenon into something sinister and deadly.

Below are eight horror novels whose imaginary friends you’d hope your child would never conjure up. 

Imaginary Friend

Imaginary Friend

By Stephen Chbosky

The Washington Post describes this masterful 700-page horror novel as “a page-turning meditation on human suffering whose spiritual dimension does not become fully apparent until the entire story has been told.”

This New York Times bestseller follows a seven-year-old boy named Christopher and his mother, Kate Reese, who seek haven in Mill Grove, Pennsylvania, after fleeing from an abusive household.

In a seemingly peaceful community, Christopher finds himself drawn to explore the woods at the edge of town after he notices a pair of fresh footprints leading down a trail. It is a decision that will alter him forever.  

He disappears for six days and reemerges from the woods with practically no memory of what happened to him; he merely remembers that a “nice man” helped him find his way out.

He is left with a voice in his head that urges him to complete an important goal by Christmas: build a treehouse in the woods. Although Christopher isn’t sure why, he knows that if he fails to complete his task, very bad things are bound to occur.  

With incredibly vivid descriptions, religious allegory, complex characters and a gradual build-up that explodes in an epic conclusion, Imaginary Friend is an unsettling read that you’ll be thinking about long after turning its final page.

Small Spaces

By Sarah Epstein

This YA psychological horror debut centers around 17-year-old Tash Carmody, who as a child, witnessed six-year-old Mallory Fisher get lured away from a carnival by someone Tash named Sparrow.

Although Mallory emerged from a hiking trail seven days later, the sweet, bubbly girl she had been before was gone—in her place, a frightened, distrustful, and mute child emerged. But no one was ever arrested in connection with the abduction.

An overactive imagination was to blame for Tash’s manifestation of a kidnapper that was never found. But when Mallory, now 15 years old, comes back into Tash’s life, suddenly Sparrow also emerges.  

Is Sparrow a figment of her imagination produced by unprocessed childhood trauma, or does Sparrow exist outside of her mind’s constraints? Regardless, Tash has a feeling that Sparrow is capable of immense harm.

Disconcerting and clever, this horror thriller will have your heart racing as you decipher what is real and what is not.
