Halloween is Saturday, and one of the best ways to celebrate is by watching horror movies.

Here's my list of the Top 13 best scary flicks of all time. Let's count them down, one scream at a time.

1. “Psycho” — Alfred Hitchcock created the mother of all slasher flicks. Based on the novel by Robert Bloch, the script by Joseph Stefano is part drama, part thriller featuring Janet Leigh and Anthony Perkins as mama's boy Norman Bates. Bernard Hermann's memorable score helped make it the scariest film of all time. To this day, I think about “Psycho” every time I take a shower.

2. “The Exorcist” - This 1973 shocker made a star out of Linda Blair. William Peter Blatty adapted his novel for director William Friedkin. “The Exorcist” is a head-spinning masterpiece that's still scary to this day. And it features the horror genre's most frightening villain - a child.

3. “The Shining” - Who can forget Jack Nicholson's portrait of a deranged, possessed husband and father? This Stanley Kubrick masterpiece from a Stephen King novel made me afraid of strange hotels and the haunted secrets they keep.

4. “Halloween” - From the famous Casio theme song to Jamie Lee Curtis' scared-yet-tough heroine, “Halloween” is the quintessential film for our scary holiday. Writer-director John Carpenter created the bogeyman of our generation - Michael Myers. Rocker turned director Rob Zombie tried to re-energize the franchise in 2007, but what he came up with paled in comparison to Carpenter's vision.

5. “Night of the Living Dead” - If “Psycho” is the mother of all slasher films, this is the granddaddy of all zombie flicks! George A. Romero's 1968 work of art served as a metaphor for the Vietnam War. Since then, every zombie film is expected to have sociopolitical allegories. Indeed, Romero changed the way we view the undead.

6. “Jaws” - This is horror in the sea crafted by an unknown director named Steven Spielberg. When the film came out in 1975, it signaled the emergence of summer blockbusters. If “Psycho” made us afraid to take showers, “Jaws” made us afraid to go into the ocean. Truth be told, every time I need a quick jolt, I turn to this intelligent popcorn flick.

7. “Alien” - This is terror in space! Director Ridley Scott's breakthrough 1979 film provides a great mix of horror and science fiction. Sigourney Weaver's Ripley is one of the best action heroes in the history of cinema.

8. “The Silence of the Lambs” - Who can forget Hannibal Lecter? This is a smart serial killer film punctuated by great performances from Jodie Foster and Anthony Hopkins. “The Silence of the Lambs” is only one of three films that have won the top five Oscar categories: Best Picture, Best Director (Jonathan Demme), Best Actor in a Lead Role (Hopkins), Best Actress in a Lead Role (Foster) and Best Adapted Screenplay (Ted Tally adapted Thomas Harris' novel).

9. “Evil Dead II” - Writer-director Sam Raimi created a diabolically funny sequel that effectively mixed horror and comedy. Raimi tried to use the same formula with the recent “Drag Me to Hell,” but the 1987 film remains as one of my favorite films from the director. Sorry “Spider-Man” fans!

10. “Rosemary's Baby” - Director Roman Polanski's baby is a paranoia horror classic that is as relevant today as when it was released in 1968. Mia Farrow splendidly portrays a waif in distress.

11. “Poltergeist” - This is a creepy haunted house movie. As soon as you hear the then 5-year-old Heather O'Rourke say “They're heeeere,” you know you're in for an entertaining ride.

12. “An American Werewolf in London” - Many films have tried to imitate this classic but none can match the ferocious intensity of director John Landis' masterwork. Even Michael Jackson was inspired by this 1981 film.

13. “A Nightmare on Elm Street” - This film introduces Freddy Krueger, the bogeyman who haunts us in our sleep. This 1984 movie also features a young Johnny Depp, who appears as one of the first victims.
