There's nothing quite like a chilling screen tale to help you beat the summer heat. Because even in the warmest weather, a good cinematic scare can still give you as much gooseflesh as a snowstorm.

Throughout the month of July, Netflix is bringing some new slasher action to the streaming scene with the "Fear Street" trilogy — three films that blend together centuries of scares in R.L. Stine's haunted little town of Shadyside for one thrilling tale. It's got masked killers, a fabled witch, a gnarly curse, and a group of teens who dare to discover the truth behind it all. In other words, there's plenty to love about "Fear Street."

And there are plenty of other scary movie options available to stream as well, from twisty thrillers to eerie sci-fi stories to films that will make you question your own reality. So, to help guide your spooky movie marathon, here's a look at some of the best horror gems on Netflix that you need to watch at least once.

It doesn't take any jump scares or boogeymen for "The Killing of a Sacred Deer" to frighten the daylights out of you. Yorgos Lanthimos' celebrated 2017 thriller brings an ancient Greek tragedy into the 21st century, following a celebrated cardiologist who's forced to confront a terrible part of his past once his family begins to suffer the consequences of his misdeeds.

In the film, Dr. Steven Murphy (Colin Farrell) befriends a teen named Martin Lang (Barry Keoghan), whose late father was Steven's patient ... until his untimely death. At first, Steven attempts to strike up a fatherly relationship with Martin, offering him companionship, gifts, and even a relationship with his beloved wife, Anna (Nicole Kidman), and children, Kim (Raffey Cassidy) and Bob (Sunny Suljic). However, Martin's presence in Steven's life becomes much more menacing once his true intentions are revealed. Martin is no mustache-twirling villain, of course, but his droll, matter-of-fact demeanor and the quiet, methodical way in which he ingratiates himself into Steven's life is unnerving to behold.

Group video chats may be more commonplace than ever right now, but when "Unfriended" first dropped in 2014, it was still a relatively novel concept. So the film was ahead of its time when it turned a friendly internet meeting into a terrifying vengeance tour. 

In the film, a high school girl dies by suicide after a humiliating video uploaded by one of her classmates goes viral. A year later, as a group of friends link up online to chat about their plans for prom night, they discover that there's a mysterious guest in the chat who can't be blocked, and that's when things really begin to spin out of control.

As they try to identify the intruder, the teens are confronted with their darkest deeds — including their roles in their late friend's death — before they are themselves subjected to a series of horrors that play out on each other's screens. With its uniquely 21st-century premise and creepy creative camera work, "Unfriended" is a thriller for the digital age.

Visionary horror director Mike Flanagan brought the concept of a living nightmare to new levels in 2016's "Before I Wake." The movie centers on a pair of young grieving parents (portrayed by Kate Bosworth and Thomas Jane) who decide to foster an orphaned boy after losing their own beloved son in a drowning accident. The couple immediately discovers that the child they've taken in, Cody (Jacob Tremblay), is a very special kid — for better and for worse.

See, Cody's dreams become a reality, and at first, this brings a great deal of joy to his new mom and dad. Shortly after he's moved in, they find their house brimming with Cody's favorite butterflies, and they even get to see a very comforting vision of their lost son. But Cody's dreams aren't always so pleasant. His nightmares become just as real too, bringing dangers untold to the waking realm. What results is a thrilling and terrifying adventure through the surreal wanderings of a unique boy's mind, along with the struggle of two parents trying to get past their own loss to help Cody and themselves survive his gift.

Popularity contests might usually be reserved for high school superlatives and political elections, but in the 2015 sci-fi horror "Circle," winning over a crowd is a matter of life or death. The film picks up with 50 people trapped in a room where they can't move off their respective markers or even touch one another without activating a lethal laser system. And what's worse is that every two minutes, a person is summarily executed by the machine at the center of them all, and the power to decide who's next on the chopping block is literally within their own hands.

As the bodies start to stack up, the people inside the circle have to use their wits to determine what exactly is happening to them and whether it's even possible to stop this cruel massacre in motion. If not, they'll have to use the precious few seconds between each slaughter to size one another up and determine which of them most deserves a chance to live. On top of its tight and terrifying framework, "Circle" also offers some intriguing commentary on social factions, deception, and the choices that are made about a person's individual value.

It's never a good sign when your small island town is suddenly plagued with tons of dead fish washing ashore and birds falling from the sky en masse, and it's even worse when one of the locals seems to be suffering from a sudden onset of rampant memory loss and dangerous hallucinations. 

In the 2020 sci-fi thriller "The Block Island Sound," the titular locale becomes afflicted with natural blights, and there's one family in particular that seems to be bearing the brunt of the human consequences of the disaster at hand. After the patriarch of the family suffers from mental collapse and then disappears into the sea, his adult children must uncover the secrets of his unraveling, just as another seems to be sinking into the same affliction ... if they can handle the truth, that is. If you're looking for a film that's dripping with dread, "The Block Island Sound" is a must-see.

Being a best-selling horror novelist requires a lot of imagination, but for Iris Blum (Paula Prentiss) in 2016's "I Am the Pretty Thing That Lives in the House," inspiration doesn't have to come from afar. The film, written and directed by Oz Perkins, picks up at the twilight of the successful author's life, when a young woman named Lily Saylor (Ruth Wilson) is hired to help care for her at her Massachusetts mansion. But in addition to being the abode of a well-renowned writer, the home has quite a history that slowly presents itself to Lily over the course of her stay.

After strange things begin happening at Iris' home, Lily starts to realize that there's a dark connection between this place and one of Iris' most beloved books. But can she get to the bottom of this harrowing ghost story before it's too late? Queue up "I Am the Pretty Thing That Lives in the House" to find out.

Renovating an old home is always a bit of a headache, but in "Girl on the Third Floor," the experience is downright nightmarish. The film centers on a troubled man named Don (C.M. Punk), who sets out to upgrade an old manor in the suburbs in hopes of starting a new life with his wife and unborn baby. But not only is he ill-equipped to handle the many serious structural issues the house has, he's also completely unprepared for the unexpected company he gets while working on the place.

As Don discovers that there's much more wrong with this vintage home than just some dated wallpaper and fritzy wiring, his own inner defects begin coming to light, and he'll have to face the consequences of his poor decisions in some terrifying new ways. This is more than your typical haunted house pic. "Girl on the Third Floor" will leave you guessing about what's in store for Don's growing family right until the bitter end.

The horrors of hunger in a hierarchical civilization have never been clearer than in "The Platform." The 2019 Spanish thriller sees its protagonist, Goreng (Iván Massagué), volunteering to participate in a social science experiment that involves him living alongside a cellmate in a prison-like tower. He learns that each day, a single platform of food is lowered from floor to floor for just a brief period of time. The higher up you are in the structure, the bigger the bounty to choose from. But if you're unlucky enough to be placed in a lower level, well, the offerings may be scarce or even non-existent, leading to eventual madness and starvation.

During his first month at the pit, Goreng and his cellmate, Trimagasi (Zorion Eguileor), are placed high enough to get their fill from the leftovers that reach their level, and the two pass their time between meals by getting to know one another. But things take a terrible turn when they wake up on a much lower level where the platform arrives with nothing left each day. From there, the stakes of this torturous system only get worse, as Goreng finds out the hard way what terrors people are truly capable of in a situation of crisis. "The Platform" is not for those with weak stomachs, but it's the kind of movie that sticks with you long after the credits roll — especially during meal times.
