Sleeping Snow

Sleeping Snow is the femslash ship between Aurora and Snow White from the Once Upon A Time, Sleeping Beauty and Snow White and the Seven Dwarfs fandoms.

Disney
Being from two different Disney movies, Snow White and Aurora never met in canon. However, the two are friends in Ralph Breaks the Internet, along with the other Disney Princesses. There are also some Disney crossover games where the two can be in the same team, depending on the player's choice.

Both Snow White and Aurora are young princesses that are known because of their beauty and charisma. Both love singing and interacting with the animals from the forest. During their movies, their are chased by their respective villanesses, who try to kill them. Both were welcomed by magical creatures, the dwarfes and the fairies respectively, in the forest. Nearly the end of their movies, both "die" but are later revived by a kiss from their respective love interest.

One Upon A Time
At first Aurora despised Snow 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. Mary holds no ill will towards Aurora 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. She tells Aurora how Charming helped her through her own sleeping curse side effects.

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
The fandom for the ship is mostly split between OUAT fans and Disney Crossover fans. The Disney side seems more popular than the OUAT side though. Some Modern AU's take inspiration from their outfits in Ralph Breaks the Internet. The Disney crossover side of the ship commonly has the two meeting or spending time with each other in the woods. 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 24 fanfics.
