If you have read the book The Dictionary of Obscure Sorrows (or read it on the internet on the official website), the book contains coined terms for emotions and states of being we all may have experienced but could never describe with words.
Nighthawk: When unpleasant thoughts you rather ignore during the day wakes you up in the middle of the night: the fear of the future, past mistakes and so on.
Wildred: A feeling of haunted solitude when you are in the middle of nowhere, and you also feel like a trespasser in a hostile environment.
Harmonoia: The feeling of anxiety when everything seems "too well and good", since you might be used of the everyday chaos.
Fellchaser: When a long-forgotten mistake sooner or later can come back to you, but you don't know what it is.
Winnewaw: When you feel skeptical after hearing good news, because the good fortune might lead to a fall, and you feel uneasy at the end of a good day, waiting for something bad to happen.
