Interesting.
I am scared central, I admit. I have read through MN 'please explain this' threads on a Wednesday morning and jumped when the boiler juddered!
However, I have never willingly subjected my DSs to 'horror'. Because I was allowed as a young child to read and, maybe rather less, see it. The nights of pure terror I suffered in rural, dark Wiltshire because I expected to wake to a shrouded monk in my room; a screaming skull on my pillow; the dark-y bit of the barn us kid had been playing in that morning, to yield The Dunwich Horror at night 😂.
With DC, I actually complained to the upper infants that a free reader, Biff and Chip, had an actual 'ghost' in it. FGS.
I saw The Devil Rides Out by 14. Because my elderly, babysitting grandad didn't realise 'it wasn't suitable'.. 😊
But Poltergeist scared the shit out of me, then Carrie, It, The Shining, and, of course, The Exorcist... and, the last I saw, Sixth Sense!
I have plenty of friends who laugh their heads off at this stuff. At 56, it can still scare the bejeezus out of me! 😂
I'd stick to 'Nightmare before Christmas' and destroy you child's street cred for ever. 😊
Tho even that was quite dark!!
