Fairies didn't always release Fairy dust from their wings whenever they moved or that would be a waste of the sparkly dust, not to mention the piles of it that would gather in houses.
So Fairy dust was only released when the Fairy wanted it to be, it could also sprinkle everywhere if they were feeling an intense kind of emotion.
Well almost cracking your head on the wooden floor counts as intense so there was a small pile of the gold dust on the ground beside her bed.
Her room was spacious, consisting of a bed, a cut wooden cupboard beside it. Two cupboards filled up the fat side of the wall, one carried all of her weird junk that she gathered gradually over the years, the other one was totally covered in vines which was another weird hobby of hers, while other Fairies filled their rooms with all sizes and colors of flowers, Eden had her vines.
