1. "Halloween" (1978)

You can't properly celebrate Halloween without watching this iconic classic. On Halloween night, a psychopath named Michael Myers escapes from the insane asylum he's been living in for the past 15 years and goes on a killing spree in his hometown of Haddonfield, Illinois. The thing that makes this film so eerie and terrifying is that the killer has no proper motive, which throws rationality out the window and suggests that nightmares can come true without warning and for no reason at all.

2. "A Nightmare on Elm Street" (1984)

Another classic slasher film, A Nightmare On Elm Street terrorizes its viewers by blurring the lines of reality. Nancy Thompson is an average high school student with a dark family history. When Nancy was little, her parents burned alive Freddie Krueger, a child rapist wrecking havoc in their town. Now, Freddie's ghost is terrorizing Nancy in her sleep and slowly killing her classmates. A Nightmare On Elm Street is more of a psychological thriller than a jump-scare flick, but it still invokes plenty of fear with the simply haunting tagline "Don't fall asleep."

3. "The Conjuring" (2013)

Based on the true accounts of demonologists Ed and Lorraine Warren, The Conjuring broke new grounds in the paranormal activity genre of horror films.

It isn't until strange happenings start occurring, like the clocks stopping at 3:07 every night or the smell of rotten meat that occasionally fills the house, that the Perrons realize something sinister has moved in with them. The movie also includes real photographs of the Warrens and the Perrons to remind the audience that an incident like this has really happened and could happen to anyone.

6. "IT" (2017)

A remake based on Stephen King's classic novel by the same name, IT encapsulates true terror by recognizing the fact that fear is personal.

7. "Hush" (2016)

Surprisingly an underrated horror film, Hush tells the story of a deaf author who is targeted by a killer in her isolated cabin. The lack of hearing in the protagonist makes the element of a killer that much scarier because it adds the element of dramatic irony - the viewer is able to perceive knowledge about the killer that the main character does not.
