how it feels to read 85 pages of a book in one sitting

reading the collected letters of shirley jackson and this is from a letter to her agent while she was working on the haunting of hill house

Many places have a "forest that shouldn't be entered." Even people who are used to working in the mountains feel there is something there. They are suddenly overcome with fear and it becomes the custom to avoid certain places. These places exist. I don't know what is there, but I think they are real . . . The world is more than we can fathom with our five senses. The world doesn't exist just for humans. So I think it is all right to have such things. This is why I think it's a mistake to think about nature from the idea of efficiency, that forests should be preserved because they are essential for human beings . . . I am concerned, because for me the deep forest is connected in some way to the darkness deep in my heart. I feel that if it is erased, then the darkness inside my heart would also disappear, and my existence would grow shallow.
