Any good book recommendations for when you cant sleep?

I really like horror and suspense books and I often bought many of those. Mainly, i like them because i think they help me face my fears and put them into perspective. I also have many classics, books of other genres and non-fiction. Mostly, when I go to the library I want to choose texts that will make me think about something. I hapoen to be really curious about slmost anything.

The problem is that I have been feeling slightly more anxious lately and I am not sleeping quite well. So I struggle to find something to read if I am awake in the middle of the night because any book I grab is too interesting or too stimulating for me to fall asleep afterwards. Obviously, I avoid horror in those cases. Not necessarily because I get too scared but because i get thrilled. Even if it is a comedy or a philosophy lecture or a science encyclopedia, I always get engaged and keep thinking about it afterwards.

I have been listening to sleep stories with an app and it works amazingly well most of the times, but I would rather keeping my phone out of the bedroom if possible. Do you have any recommendations of relaxing books you read when you cant sleep? Some very light story book or something?
