Have not seen any of these yet. Would really like to see The Witch. If you have not seen it yet, I would suggest Goodnight Mommy. Not really a jump scare but it is a really fucked up movie that left me feeling disturbed. Also surprised to learn that Krampus is a figure in Christmas folklore. I thought he/she/it was just a mini-boss that randomly spawns inside the devil room in The Binding of Isaac. Guess you learn something new everyday.
I haven't watched this one yet ,i will definitely try it, it looks scary and disturbing thank you for your recommendation
