Autistic!Luna Lovegood headcanons
Creates spells to help with sensory overloads, such as charming a pair of glasses to dim bright colours that hurt her eyes and charming a pair of earmuffs and earrings so it muffles loud noises
Creates a spell to instantly make all her clothes soft to stop them from scratching against her skin
Has trouble concentrating
Wears long necklaces with beads and small charms to fidget with
Has an agreement with the kitchen House elves who make her food that isn’t as flavourful/spicy as every one elses, and also her plate has an enchantment on it so the different foods don’t touch. In exchange for this she visits the kitchens once a week and shows them all the pretty things she’s found while walking
Collects random things she finds pretty, shells, rocks, sticks, leaves, feathers etc
Can stare into the Ravenclaw common room fireplace for hours on end looking for shapes in the flames
Likes clothing and fabric with tassels
Runs fingers and toes through the folds in fabric for comfort
No sense of direction and often gets lost on the Hogwarts stairwells so Ginny or other DA members accompany her from class to class so she’s not late
Stares into space and gets lost in her thoughts a lot
Special interest is magical creatures and can memorise a large number of interesting facts about them
Paints with her fingers and likes using many layers of paint so it creates a 3D effect to her art
Places her wand behind her ear or in her hair bun because she often misplaces it
Likes spinning and twirling as a form of stimming
Cuts the labels off all of her clothing
Writing is hard and hurts her hand when she grips the quill, so she uses an enchanted quill to take notes for her during classes, and to write her homework (this is allowed by Dumbledore to any disabled students in Hogwarts with similar issues)
