CANDYMAN (1992): The Candyman, a murderous soul with a hook for a hand, is accidentally summoned to reality by a skeptic grad student researching the monster's myth. Remember this scaring the shit out of me as a youngster!!
The Witches by Roald Dahl. Roald Dahl played a major part in my childhood, and The Witches was one of my favourites by him. It scared me, and I appreciated having a children's book that didn't flinch from fear!
