magic is real, but not what you see in the movies. magic is energy, we use spells to direct the energy in a direction to help our lives in love, luck, health and so on. spells that goes against nature like flying, teleportation, transformation and so forth, won't work.
you can look into astral projection, your physical self won't fly, but your astral self can leave your body and float around. casting a spell and you can fly though won't work. if it does, please be sure to document it.
