Fear is subjective, which makes ranking the scariest movies of all time a tricky task. The folks at GIGACalculator.com are all about numbers, and they've found a way to translate a film's fear factor into hard data. Based on their findings, these are the horror movies most likely to get viewers' hearts racing.

To compile their list of the most terrifying horror flicks, GIGACalculator.com showed movies to 150 first-time viewers while tracking their heart rates. The film selection was determined by a survey of 2500 self-proclaimed horror fanatics prior to the study.

Director Ari Aster's 2018 movie Hereditary took the top spot with pulses rising to an average of 115 beats per minutes (BPM) during viewings. For comparison: A healthy average resting heart rate falls between 60 and 100 BPM. Taking the number 2 spot was the 2004 gore-fest Saw, which jacked up heart rates to an average of 113 BPM. The Babadook (2014), Insidious (2010), and A Quiet Place (2018) rounded out the top five. You can see the full ranking below.

We’re firmly in that time of year when the air is colder, the nights are longer, and the books in our to-read pile are getting scarier. Cracking open a horror book in your comfiest chair is one of the best ways to embrace the Halloween season, and at Mental Floss, we’ve got plenty of suggestions for your next title. From genre classics that should be on everyone’s list to a few offbeat entries—including a must-read comic starring a spectacularly creepy ice cream man—here are our favorite horror books you should pick up.

1. The Penguin Book of Exorcisms // Joseph P. Laycock; $16-17

Penguin/Amazon

What better way to embrace spooky season than with this collection, which features real-life accounts of exorcisms from around the globe? When you're done, crack open The Penguin Book of Witches and The Penguin Book of Ghost Stories, which will also send shivers up your spine. —Erin McCarthy, Editor-in-Chief

2. The Witches // Stacy Schiff; $15-$17

Back Bay Books/Amazon

Few things are scarier than actual history, as Stacy Schiff's painstakingly researched and beautifully written account of the Salem Witch Trials—which began in 1692 and ended less than a year later, with 25 people dead—shows. —E.M.

Buy it: Bookshop, Amazon

3. The Haunting of Hill House // Shirley Jackson; $9-$15

Penguin/Amazon

Often described as one of the scariest books ever, Shirley Jackson's tale of four paranormal investigators who set up shop in a haunted house will fill you with creeping dread, making it the most perfect of reads for this time of year. At around 200 pages, it's a quick read—and when you're done, you can fire up one of the novel's TV and film adaptations to keep the creepiness going. —E.M.

4. Horrorstör // Grady Hendrix; $13-$14

Quirk Books/Amazon

If you’ve ever panicked while traversing the mazelike layout of your local IKEA, Horrorstör will be all too relatable. In this book, Orsk, a Swedish furniture store in Cleveland, Ohio, is the scene of some very paranormal activity, which spurs a handful of employees to brave an overnight shift to find out the origins of these malevolent spirits. It’s the perfect read for anyone who’s ever thought their 9-to-5 was quite literally out to get them. —Jay Serafino, Special Projects Editor

Buy it: Bookshop, Amazon

5. Blood Meridian // Cormac McCarthy; $10-$16

Vintage/Amazon

Awash in gruesome imagery and some of the most disturbing acts of violence ever put on the page, Cormac McCarthy’s Blood Meridian isn’t a horror tale of the jump-scare variety. Instead, it achieves pure terror by examining man’s hateful, vengeful nature under the guise of a Western. —J.S.

Buy it: Bookshop, Amazon

6. Ice Cream Man // W. Maxwell Prince, Martin Morazzo, Chris O'Halloran; $15-$17

Image Comics

The spirit of EC Comics and its lurid horror anthology titles lives on in Image’s Ice Cream Man. With his sharp white uniform and truck full of sweets, the titular ice cream peddler meddles in the lives of others, often with terrifying results. —Jake Rossen, Senior Staff Writer

Buy it: Bookshop, Amazon

7. The Ruins // Scott Smith; $14-$16

Vintage

Tourism takes a horrific turn in this unsettling potboiler about a group of American tourists who find that an ancient Mayan site isn’t too welcoming to visitors—and neither are the acidic vines that singe both skin and soul. —J.R.

Buy it: Bookshop, Amazon

8. Cujo // Stephen King; $15-$17

Gallery Books/Amazon

Published in 1981, this New York Times bestseller is not for the animal lovers out there. It starts in the town of Castle Rock, Maine, which becomes terrorized by a once-friendly Saint Bernard. While this is all happening, the Trenton family moves into the seemingly idyllic town only to realize it isn't as lovely as it appears. Parents Vic and Donna are having marriage issues, and their son Tad can't sleep due to the terrors coming from his closet. Little do they know that the real monster is waiting for them outside. —Elaine Selna, Commerce Writer

9. Ring // Koji Suzuki; Prices vary

Vertical/Amazon

Before the Japanese horror movie and the American remake, Ring was a bestselling novel. Published in Japan in 1991, the book turned the VCR into an instrument of terror at the height of its popularity. There are major differences between the original story and its screen adaptations, but the basic plot should be familiar to any horror fan: After watching a cursed video tape, the main character has seven days to solve the tape's mystery and escape death. —Michele Debczak, Senior Staff Writer

Buy it: Amazon

10. Let the Right One In // John Ajvide Lindqvist; $14-$18

St. Martin's Griffin/Amazon

John Ajvide Lindqvist’s 2004 Swedish novel chronicles the friendship of a young boy named Oskar and his enigmatic new friend, Eli, who happens to be a very old vampire. Let the Right One In has all the trappings of a grade-A horror story—bloodlust, mystery, plot twists, etc.—set against a backdrop of real-world issues, from bullying to alcoholism. The protagonists may be children, but the adult themes of this novel gear it towards older readers. —Ellen Gutoskey, Staff Writer

Buy it: Bookshop, Amazon

11. Carrie // Stephen King; $7-$14

Anchor/Amazon

King's debut novel from 1974 still ranks among his best. It revolves around a teenage outcast named Carrie White who gets bullied at school and has to deal with an abusive mother at home. Any hope she has of fitting in is soon dashed as she begins developing strange telekinetic abilities. —E.S.

15 Extremely Valuable Funko Pop! Figures That Might Be Hiding In Your Collection

In the 1990s, collectors salivated over Beanie Babies. In the 2000s, it was Pokemon. Today, the collectibles market is dominated by Funko Pops!, the ubiquitous vinyl figures that turn pop culture characters into block-headed, saucer-eyed cute bombs.

While Funko has a deep bench of licenses, many figures are exclusive to retailers, available for a limited time, or are otherwise hard to find. After perusing recent auction sales and Funko online price guides, we’ve excavated a few figures that are being bought and sold for stacks of cash larger than the toys themselves—and could be hiding in your very own collection. Take a look at 15 of the most sought after and valuable Funko Pop! figures that could net you a small fortune on the secondary market.

1. Ghost Rider Metallic Freddy Funko // $4210

The spirit of vengeance was unleashed as an ultra-exclusive variant edition that's a mash-up of the Marvel hero with Funko mascot Freddy Funko. Released in 2013, it was limited to just 12 figures. As a result, it’s a high-ticket item. The Pop Price Guide, which tracks Funko Pop! values and sales, estimates it at $4210.

2. She-Ra // $690

Funko

The warrior princess of the 1980s Masters of the Universe spin-off cartoon made a splash in 2013. The figure wasn’t a limited edition, but so many fans snapped her up that she’s hard to find.

3. Mike Wazowski Glow-in-the-Dark // $1960

The jolly green creature from 2001’s Monsters, Inc. was available in a limited glow-in-the-dark edition beginning in 2011, but collectors had to go on a scavenger hunt—only 480 were produced.

4. Reggae Rasta // $1200

Walmart

This Bob Marley-inspired figure has been sought after by collectors for sporting a limited-edition green outfit instead of the multi-colored one in the image seen above. That regular version sells for around $400.

5. Holographic Darth Maul // $5070

The horned villain from The Phantom Menace, 1999’s Star Wars prequel, got the glow-in-the-dark treatment from Funko in 2012. San Diego Comic-Con attendees had first crack at the variant, which was limited to 480 figures.

6. Master Chief // $650

Funko

The hero of the Halo 4 video game was a Blockbuster Video exclusive and commands $650 on the open market.

7. Ken Griffey Jr. Bronze // $3150

One of Major League Baseball’s most celebrated players got the Pop! treatment in 2018, with just 24 gold-finish variants made for fans at Seattle's Safeco Field (which was renamed T-Mobile Park in late 2018). The current market value is $3150.

8. Headless Ned Stark // $980

Funko

One of the most tragic and unexpected deaths on Game of Thrones was immortalized in this 2013 San Diego Comic-Con exclusive, which features the head of the Stark family and his detachable melon. The Pop Price Guide has valued Stark at $980.

9. Black Ranger Freddy Funko // $1850

This hybrid of Funko mascot Freddy Funko and the Mighty Morphin’ Power Rangers was limited to fans attending the Funko Fundays event at 2017's San Diego Comic-Con. Only 24 were produced, which is why they’re extremely difficult to find, even on auction sites.

10. The Notorious B.I.G. Metallic // $1930

Funko

The late rap headliner got the deluxe treatment in 2011, with a metallic coat and hat version that was limited to 240 pieces. (The regular version is pictured.) Its listed value is $1930.

11. Batman Blue Metallic // $1400

The Dark Knight is looking a little more ostentatious in this 2010 San Diego Comic-Con offering, with a shiny blue cowl and accessories.

12. 1970s Elvis Presley Glow-in-the-Dark // $2170

Funko

A 1970s-era Elvis (above) comes in a special glow-in-the-dark version that has an estimated value of $2170. Another limited chase figure that depicts him at the height of his powers in the 1950s will run you as much as $1700.

13. Clown Dumbo // $5900

The ear-shaming of Disney’s 1941 animated classic Dumbo continues to strike a chord with people. The 2013 edition of Dumbo in clown make-up was limited to 48 pieces for San Diego Comic-Con attendees.

14. Planet Arlia Vegeta // $3500

Funko

The flame-haired Vegeta from Dragon Ball Z was exclusive to fans at the 2014 New York Comic Con and the Toy Tokyo store in New York City.

15. Bob’s Big Boy // $850

This iconic advertising character was a San Diego Comic Con exclusive in 2016. Only 1000 were made.
