It's sort of hard to believe, but Halloween is no longer that far away.

To get you in the mood for the creepiest month of the year, Amazon Prime Video is releasing four original horror movies, all of which have been produced by Blumhouse (the company behind the Paranormal Activityand The Purge), and all of which will released in October.

On Wednesday, they dropped the trailers for all four films.

From the Black Mirrorvibes of Black Boxto the possibility of a family curse in Evil Eye, here are the films that will make up the upcoming "Welcome to the Blumhouse" series...

Nocturne

Written and directed by Zu Quirke and starring Sydney Sweeney, Nocturne's music academy nightmare has faint echoes of 2018's The Perfection.

"Inside the halls of an elite arts academy, a timid music student begins to outshine her more accomplished and outgoing twin sister when she discovers a mysterious notebook belonging to a recently deceased classmate," reads the description.

Nocturne comes to Prime Video on Oct. 6.

Black Box

Osei-Kuffour Jr.'s Black Boxfeatures the kind of technology-based horror that's reminiscent of Black Mirror's "Playtest" episode.

"After losing his wife and his memory in a car accident, a single father undergoes an agonizing experimental treatment that causes him to question who he really is," reads the blurb.

Black Box comes to Prime Video Oct. 6.

The Lie

Veena Sud's The Lielooks less horror and more crime thriller, with echoes of Apple TV+'s recent series Defending Jacob.

"When their teenaged daughter confesses to impulsively killing her best friend, two desperate parents attempt to cover up the horrific crime, leading them into a complicated web of lies and deception," the description reads.

The Lie comes to Prime Video Oct. 6.

Evil Eye

Evil Eyeis based on an Audible Original production written by Madhuri Shekar, which won the Audi Award for Original Work in 2020.

"A seemingly perfect romance turns into a nightmare when a mother becomes convinced her daughter’s new boyfriend has a dark connection to her own past," reads the blurb.

Evil Eye comes to Prime Video Oct. 13.
