This book is a combination of many short stories. Those short stories are based on folk tales, supernatural experience of different individuals. I've gathered most of these stories from internet. There might be some stories you are familiar with but they are different from original version.
Read them if you feel comfortable. If you think horror and supernatural things are not your thing then I suggest you to avoid reading them. It might not be for light hearted people.
If you decided to read them then read on your own responsibility.
