Deep Indigo

Something told Mara they should've hurt. A strange whisper in the back of their mind said that they should have been in terrible pain, but nothing felt out of place. A tingly feeling settled into their limbs, but it was more like getting injured in a dream; their brain telling them something was wrong when in reality, nothing had happened.
The outside world filtered in slowly as they opened their eyes and propped themselves against a wall. The first strokes of morning poured through the frosted windows, almost tricking them into thinking that they were at home and just fell asleep in a weird spot. It wouldn't have been the first time.
But, their sleep-idled brain couldn't explain away the rows of desks in front of them.

(Mara wakes up after an accident and notices that things aren't how they should be. The most obvious thing tipping them off is a weirdly friendly, floating boy.)
