Sleeping Snow

Sleeping Snow is the femslash ship between Aurora and Snow White from the Once Upon A Time and Disney fandoms.

Canon
At first Aurora despised Snow White (Mary Margaret in Storybrooke) and her daughter Emma when she was told by Mulan that they were responsible for Philip's death. Despite them being cleared by Lancelot, Aurora's anger and refusing to believe that the are innocent nearly had her kill Mary in an act of vengeance, until she realizes that Mary and Emma are truly innocent of the crime they were accused of. Because Aurora's actions were due to a miss understanding, Mary holds no ill will towards her as they, along with Emma and Mulan journey together. Where Mary watches over Aurora while she sleeps. After seeing Aurora suffering from nightmares and does what she can to calm her, Mary explains to her that it is an unpleasant side affect from the sleeping cures, and because she too was a past victim of it, Snow tells Aurora how Charming helped her through it.

When Aurora and her baby son, Philip Jr., began to live in Storybrooke, she and Mary/Snow have started to attend parenting classes with Cinderella. Because Aurora is still adjusting to the ways of the modern world, Snow helps her through it whenever she can.

Fanon
Because of their "enemies" to friends relationship in the Once Upon A Time series and are two Disney owned and based characters that are Disney Princesses, that have been femslash in Disney crossover ships that focuses on its princesses, there are fans who use the ship and some of its titles in both fandoms. Even though the Disney side of the ship is shown to be more supported and well liked than it is on the OUaT side of it. Which is why there have even been those who feature the two as their other cameo counterparts in other canon Disney crossovers and draw from universes, like Kingdom Hearts (where they are two of the first seven Princesses of Hearts), Sofia the First, Descendants (where they both have brief appearances in the first film) and the Wreck-It Ralph sequel film, Ralph Breaks the Interest, that sometimes has a few Disney fans place Snow White and Aurora in the modern, style clothes that the netizen versions of them are seen wearing.

The Disney crossover side of the ship commonly has the two meeting or spending time with each other in the woods with their animals watching them. Like with their princes, the songs they sing guide either one of them to each other.

On AO3, the Disney side of the ship has 15 fanfics.
