Thakurmar jhuli brings back a lot of memories from my childhood and they were quite wholesome to be honest. The stories in that book are so good, but the best I think will have to be "Shakchuni Golpo" ( Shakchuni - witch, Golpo - story in Bengali), it's a classic horror story about a witch who wanted to marry a Brahman and take care his family. But the Brahman was married, and so the witch cursed the wife by trapping her and shape shifting into her. But then an educated priest came and threatened the witch to bring the wife back. At the end, the wife was back and the witch went away. So I would highly recommend to all to read this book
