I’m talking about things which scared the bejeezus out of you at the time and you would still hate to encounter as an adult- no doubt irrationally. I have two examples and suspect if I revisited them, they wouldn’t be as bad as I remember. I won’t though - still too scared!
The first is a book called A Candle in Her Room. It’s about some sisters who have an vile, evil wooden doll in their house and horrible things keep happening to them. It was a children’s book but I found it terrifying. I’m a middle-aged woman but NOTHING would make me read it again. The thought makes me want to vomit.
The second is a public safety film called Apaches which was shown in the 1970s. It involved a group of children dying one by one on a farm (all had horrible accidents)... I know I will never watch that film again even though it’s readily available on YouTube. My terror is too great.
Anyone else?
