I’m struggling to think of many ‘scary’ films. But I can detach the screen from reality so will feel tense or excited or get jump-scares or what have you, but actually “scared” not so much.
Video games on the other hand… I played the demo of Resident Evil 5 (I think?), you’re trying to escape from a creepy old house and there’s things like a bedroom full of mannequins, you turn away and turn back and they’ve moved. The ending I got, I got the back door open and then the maniac in the house grabbed me, I about soiled myself. People play the full game on VR; two words, second word “that.”
The other one that gave me the willies was Alien Isolation. Wandering around a derelict spaceship or similar, spent like an hour and a half quietly shitting myself, didn’t see a single alien.
