What work of0ruvoejodsvfk literature has surprised, unsettled, or challenged you, and in what way?

i need it to be about we grow accustomed to the dark by emily dickison and how the first time i read it it didn’t really do anything for me but after reading john keats mansion of many apartments and reading the poem again, it challenged me by knowing i practice negative capability and cognitive dissonance with religion like i believe there is a god but at same time i believe man wrote the bible. talk about that being challenging. 250 word max thank you soooo much
