One possibility could be "wodan dreame".
Before getting to this point I'd like to add that whereas the spelling "nightmare" is indeed recent (see the corresponding Google ngram), more archaic spellings are reported in the OED; viz "niȝt-mare" (1290), "nytmare" (1340) and "Nyghte Mare" (1440).
Leaving aside older spelling of "nightmare", I also came across an article on Google books suggesting that when preceded by "wod" or "wodan", then the dream turned out to be a nightmare...
This is in line with Wodan's main domains of death, war and afterlife. The article oldest quote is circa 890 and there are also quotes from Ælfric of Eynsham. Unfortunately the pages after 161 are not available from Google books.
Update
Then, starting with the 18th century the Latin world "incubus" was in use. But that's not Old English any more I'm afraid. It's still used in Italian (under the form incubo) actually.
Lean In: Women, Work, and the Will to Lead is a 2013 book written by Sheryl Sandberg, the COO of Facebook.
According to the New York Times (Making a Word Meme):
“Lean in” is the idiom of the moment for headline writers, the Twitterati and New Yorker cartoonists. ...An avalanche of publicity accompanying the book’s release in March helped the expression gain a toehold in the cultural vernacular, but the phrase seems to have taken on a life of its own, even among (perhaps especially?) those who have not read the book.
The phrase had a life before Ms. Sandberg used it. It was frequently invoked in sports (lean in to the slope, lean in to the wave) and evolved into a metaphor for embracing risk, said Ben Zimmer, executive producer of the Visual Thesaurus and Vocabulary.com, and language columnist for The Boston Globe.
Ben Zimmer writes:
In winter sports like snowboarding and skiing, you might want to "lean into the turn." And "leaning in" is also seen as a good move in sports as diverse as rowing, boxing, football, baseball, horse-riding, riflery, motorcycling, and running.
From these different activities comes a general picture of "leaning in" (or "leaning forward") as a stance that suggests embracing risk and not shying away from difficulty or obstacles in one's path. It's not surprising, then, that "leaning in" should get applied to the business world.
He stated that the earliest use he could find to this metaphorical transfer comes in a 1941 issue of Princeton Alumni Weekly.
Dave Walton of Wordorigins.org states:
A possible progenitor for the Sandberg's use of the phrase is from interactive television, which has for at least 15 years been describing the difference between 'lean back' and 'lean forward' to denote the difference between TV and the Internet.
That might explain the Ngram takeoff in 1965 (with lean forward leading the pack).
Is lean out paired with lean in? Most likely, seeing the above.

In American English, Noel is defined as
In ordinary speech, it can be used as a synonym for Christmas, but would be considered a bit poetic. It is not very commonly used outside of the context of carols, cards and decorative uses (signs, headlines, ornaments).
Note that, while the diaeresis form Noël is often found on pre-printed cards and decorations, it is not commonly used in written English in the US (and is difficult to find on US keyboards).
