Both fiction and non, all ages and genres. Sleep-walking, night terrors, sleep paralysis, etc. Real stuff, not magic stuff for this list. ;) And no insomnia - that's covered elsewhere (see below).

Please limit this list to real-world sleep disorders (likely more realistic fiction, non-fiction, than fantasy), and do not include subjects such as:

"Dream Walking" (YA - https://www.goodreads.com/list/show/8... General - https://www.goodreads.com/list/show/2...),
"Astral Projection" (https://www.goodreads.com/list/show/1...),
"Dreams" or "Dreaming" (YA/MG - https://www.goodreads.com/list/show/;... General - https://www.goodreads.com/list/show/8...)

If a character in a fantasy story sleepwalks, it's fine to include so long as it is 'garden variety somnambulation' described. Fradulent cases of sleepwalking (pretended) are also fine.
