Couldn't think of "Arabian Nights" as it is actually called "One Thousand and One Nights" in English and in many many other languages, including the original.
In trying to think of a term for nocturnal people, I entered nightwatch because that role is often perfect for people who like being nocturnal in their lifestyle. Quizmaster already said why it's high % but this is another reason likely.
In NZ it’s a “bedside table” - but I’ve heard Americans say “nightstand” enough to get it (even if I didn’t quite realise that’s what the term meant!).
For some reason I couldn't think of "nightmare" and was trying different versions of "night terror"....the much more obvious answer staring me in the face!
Would you consider “nighthawk” in addition to “night owl”? I think both are quite common. Yes, I entered hawk and felt robbed from a perfect score so this is a seeking justice request.
Didn't want to reset the stats.
Eventually, this will be the least-guessed answer.
