Netflix and Amazon Prime Video are going all out for Halloween this year

However, Amazon's new TV series Lore, a true-horror series based on author Aaron Mahnke's podcast of the same name, will help tide people over when it drops on Friday the 13th.

The anthological series explores the horrifying reality behind common folklore, and retells them through interviews, dramatic reconstructions and animation.

While David Fincher's new Netflix series Mindhunter has been labelled as a thriller, the subject matter – which delves into a real-life department of the FBI which sought to catch criminals by understanding the psychology of serial killers and rapists – is about as scary as they come. Prepare to be creeped out when it drops on the 13th.

Amazon has already released the first season of The Exorcist TV series, which expands upon the universe created in the original film with a modern day tale of demonic possession. The good news is, it is much better than anyone could have expected.

Naturally, both services are bulking up their catalogues of horror films throughout the month.

Check out a full list of each streaming service's spookiest additions for the month of October below.
