Warning: MTV's new crime thriller may cause insomnia.

"Eye Candy," starring triple threat Victoria Justice, debuted this week, and tbh, we didn't sleep a wink after watching it. Justice plays Lindy, a pretty computer whiz/hacker who tries her hand at online dating -- and attracts the attention of a serial killer.

There were already some terrifying glimpses of the maniac's madness: In one scene, he walks into the apartment of his latest date (we only see him from behind because, you know, that’s part of the mystery) and quickly sizes up the soon-to-be victim.

"That mouth…so moist. So alive," he thinks to himself in the eeriest voiceover ever. "I want to chew on it. Taste it."

Creepy, right? We thought so. And that got us reminiscing about all the other unsettling onscreen quotes that have caused us many a sleepless night. Take a look at the very best -- but first, be sure to lock your front door and all the windows. And if the phone rings, whatever you do, don't answer it.

"Do you like scary movies?" -- Ghostface in "Scream"

It was the scene that launched Wes Craven's uber-successful "Scream" series: High school cutie Casey Becker (Drew Barrymore) plays along when she gets a flirty phone call from a mystery man, who first inquires about her preferred choice of cinema. But sh** gets real when he asks her name…because he wants to know who he's looking at. Like all good psychopaths, he then suggests the two play a game: He begins to quiz her on horror movies, and when Casey gets an answer wrong, her boyfriend is slaughtered in the backyard. So what happens to the damsel in distress? In case you live on Mars and never saw the flick, here's a hint: Barrymore's role was a special cameo, and she only appears in the movie's first scene. See what we mean about answering the phone?

"Heeeere's Johnny!" — Jack Torrance in "The Shining"

A writer (Jack Nicholson) and his family arrive at the historic Overlook Hotel in Colorado, where the wordsmith hopes to use the winter solitude to finish a play in between duties as the inn's new off-season caretaker. Unfortunately, the place causes him to go bonkers and hunt down his own flesh and blood (key word: blood). There were plenty of disturbing moments (how about that kid chanting "redrum"?), but this one went down in cinematic history: When Jack's wife (Shelly Duvall) barricades herself in the bathroom, he chops through the door with an ax -- and channels his inner Ed McMahon to announce his arrival.

"I'm your number one fan." -- Annie Wilkes in "Misery"

When famous author Paul Sheldon (James Caan) crashes his car near snowy Silver Creek, Colorado, he's rescued by a middle-aged woman (Kathy Bates) who takes him back to her remote home. The injured scribe is totally in luck: Annie is a nurse and, as she proudly proclaims, an avid admirer of his work. Too bad she's cockadoodie CRAZY.

"I do wish we could chat longer, but I'm having an old friend for dinner." -- Hannibal Lecter in "The Silence of the Lambs"

Sure, the obvious choice is that line about liver, fava beans and a nice chianti. But the psychiatrist-turned-serial-killer (Anthony Hopkins) spouted a torrent of terrifying passages as he matched wits with FBI Academy student Clarice Starling (Jodie Foster) -- even when his mouth was covered by that mask (pictured above). Among them was this line, uttered in the very last scene: After escaping the hands of the law, Lecter phones a startled Starling -- most memorably, he asks, "Have the lambs stopped screaming?" -- but their conversation is soon cut short. The reason? The cannibal has gone all the way to Bimini to track down his greatest nemesis -- Frederick Chilton, who made Lecter miserable at the Baltimore State Hospital for the Criminally Insane -- and it's time to make him a meal.

"It rubs the lotion on its skin or else it gets the hose again." -- Buffalo Bill in "The Silence of the Lambs"

Dr. Lecter may have stolen the show in the Oscar-winning film, but he certainly wasn't the only sociopath in town: Bill (who went by the aliases Jame Gumb and Jack Gordon) is kidnapping women just so he can skin them and use their carcasses to make a lady suit. For himself. The moth-loving madman (Ted Levine) eventually abducts a U.S. Senator's daughter (Brooke Smith) and, like his previous victims, forces her to await her fate in a pit dug 15 feet deep in his cellar floor. But it's dark and dry down there, so Bill/Jame/Jack frequently lowers down a basket that contains a bottle of moisturizer -- and demands she use it. Because, you know, what's the point of having a lady suit if it’s not smooth and supple?

"I see dead people." -- Cole in "The Sixth Sense"

M. Night Shyamalan's supernatural thriller doesn't focus on murderers and boasts nary a drop of blood, but it does contain one of the most unsettling movie quotes ever thanks to nine-year-old Cole (Haley Joel Osmet), who reveals his astonishing extra sense to child psychologist Malcolm Crowe (Bruce Willis). We weren't surprised when the good doc eventually helps Cole accept his, umm, gift -- but we never expected the flick's twisted, curve-ball ending that made us stand up in the movie theater and shout, "WHAT?"

"They're heeere." -- Carol Anne in "Poltergeist"

Again, this movie didn't feature killers and carnage -- just a bunch of ghosts who get really PO'd when a family moves in on top of their burial ground. The spooks are first noticed by little Carol Anne (Heather O'Rourke), who kneels in front of a static-filled TV set and memorably announces their arrival.

"I took a souvenir: her pretty head." -- John Doe in "Se7en"

Kevin Spacey's murderous character is obsessed with the seven deadly sins -- throughout the film, he strikes in the name of "Gluttony," "Greed," "Sloth," "Lust" and "Pride" as homicide detectives William Somerset (Morgan Freeman) and David Mills (Brad Pitt) follow his trail of butchery. But John Doe hits close to home when he kills in the name of "Envy" -- in a barren field, he calmly explains to Mills that he'd visited the detective's home that very morning and "tried to play husband" with his wife. "I tried to taste the life of a simple man," he says chillingly. "It didn't work out." To say the least.

"Happy Fourth of July, Julie!" -- Ben Willis in "I Know What You Did Last Summer"

Independence Day is usually marked by fireworks and parades, but we aaall know what Julie (Jennifer Love Hewitt) and her pals did during the '96 holiday: mow down an innocent pedestrian and dump his body in the river. The problem (besides the fact that a hit-and-run is a felony): The guy survived, and he's now seeking revenge by slaughtering the gang one by one. The bloodbath culminates on the very anniversary of the accident -- July 4 -- when Julie finally comes face-to-face with the hook-wielding maniac. Suffice to say, he's not in the best of moods -- but he does wish her a pleasant holiday. *shiver*

"I like to dissect girls. Did you know I'm utterly insane?" -- Patrick Bateman in "American Psycho"

Patrick is Ivy league-educated (he went to Harvard), rich (he's a NYC investment banker) and good-looking (HELLO, he's Christian Bale). He's also a sadistic serial killer, offing homeless people, prostitutes, models and more. He certainly isn't ashamed of it: During dinner with a co-worker (Jared Leto), the Huey Lewis and the News stan happily reveals one of his hobbies -- and even alludes to his lunacy.

"A boy’s best friend is his mother." -- Norman Bates in "Psycho"

The handsome young proprietor of the Bates Motel (Anthony Perkins) welcomes a pretty guest named Marion (Janet Leigh) in Alfred Hitchcock's classic 1960 thriller. Before long, they begin chatting about Norman's life and hobbies -- mostly, he enjoys taxidermy and spending time with his mother (and really, who doesn't?). When Marion asks if he ever gets out of the house and hangs with pals, Norman utters this legendary line -- and proves that someone has serious mommy issues.
