Ooh, this is easy. Fortunately for you I used to stay with my grandmother as a young child, who subjected me to many inappropriate and unsettling films before sending me off to bed down a very long corridor. Also, fortunately for you I have a very good memory and was left scarred by these films.
Don't go to Sleep - a film about a girl Jennifer who was burnt alive in a car crash after one of her siblings tied her shoelaces together and she was unable to escape. She then returned as a ghost in order to punish/kill off other family members. I distinctly remember a pizza cutter and a bannister was involved.
Crowhaven Farm - a film about suspected witches. The plot culminated in a woman being crushed to death as a wooden door was placed on her and villagers slowly added rock after rock.
The Christmas Tree - a cheery little festive film about a boy who had leukemia as a result of radiation stemming from nuclear fall out. Having been given months to live, his family went about indulging his final wishes, which included buying him a couple of wolves. He died under the Xmas tree on Christmas Eve. The next day his parents woke to find him, his presents remained unopened, his wolves howled loudly and mournfully as more bombers flew overhead, no doubt carrying more radioactive bombs in which to deliver misery to another child. And, Yes, this film was on on Christmas Eve!
Threads - another cheery little nuclear war film, whereby a nuclear bomb is dropped upon Sheffield. People wet themselves, blood pours down the hospital steps, people suffer radiation poisoning, and amongst this, a young pregnant lady named Ruth is abandoned by her boyfriend and has to survive in an apocalyptic post nuclear world. She sells her body for rats to eat and, as I recall, gives birth alone to a deformed/unwell or stillborn baby.
