If people liked Wolf Creek, are you aware that there is a sequel (not as good) as well as 2 seasons of a TV series which came on Sky around 10 years ago I think? It has the same killer and explains more about his back story. Obviously stay away if the first film scarred you 😅
I was going to add:
Exorcism of Emily Rose, when the boyfriend wakes up in the night when visiting Emily at the dorm, and she's lying on the floor in a rigid pose staring at him with black eyes. There were many scenes in that film that freaked me out, it's one of my fave horrors.
The Grudge when she's at the office late at night going down (or up) in the lift, and the little Japanese boy appears in the lift window as she passes several floors! Again, same Japanese boy appears in her bed when she looks into the covers
Paranormal activity 2, when Kate is possessed and goes to take Hunter, the way she appeared in her sister's house and charged at her sister while she was holding Hunter in her arms
Paranormal Activity 3 when Toby is terrorising the young sisters. And when the boyfriend is filming at the mum's parents house at the end and bumps into loads of old women in the garden shed or something
Texas Chainsaw Massacre, the one with Jessica Biel, where leather face confronted her wearing the face of her boyfriend as a mask!
