Nightfee

Nightfee: noun. When Johann Wolfgang von Goethe created the word 'nightmare' by combining the word 'night' with the Old English word for a goblin, he also created the word 'nightfee', by adding the German word for a fairy, thereby creating a word meant for a pleasant dream. However in an attempt to undermine his work by German artists and authors, who weren't receiving any attention because of Goethe, they worked collectively to prevent the word nightfee from being used in everyday language. They succeeded and the word has since disappeared. However they still died alone, poor and helpless, so sucks to be them.
