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.
