"Then a nurse came and sat on her bed with a clipboard and went through reams of questions relating to her state of mind. Nora decided to keep her experience of the Midnight Library to herself because she imagined that it wouldn't go down too well on a psychiatric evaluation form.

What exactly does "go down too well" mean in this context? I would like to know its literal, word-for-word meaning and then its natural, common meaning. Is "go down well" an idiom, is it used in other contexts?

You have a typo in both your title and your copy of the text. It should be "imagined", not "imaged". You still have plenty of time to change both misspellings using the "Edit" facility.
