Ever heard Ondine's Curse (or Undine's Curse or c
ongenital central hypoventilation syndrome or CCHS, or primary alveolar hypoventilation)?
Apparently it's a disorder that whenever the afflicted falls asleep, they can't breath and die. The name stems from a German myth. I'm too lazy to type it up, so here's a quote from the Wikipedia article.

In a German tale known as
Sleep of Ondine, Ondine is a
water nymph. She was very beautiful and, like all
nymphs, immortal. However, should she fall in
love with a mortal man and bear his child, she would lose her immortality.
Ondine eventually falls in love with a handsome
knight, Sir Lawrence, and they are married. When they exchange vows, Lawrence vows to forever love and be faithful to her. A year after their
marriage, Ondine gives birth to his child. From that moment on she begins to age. As Ondine’s physical attractiveness diminishes, Lawrence loses interest in his wife.
One afternoon, Ondine is walking near the
stables when she hears the familiar snoring of her husband. When she enters the stable, she sees Lawrence lying in the arms of another woman. Ondine points her finger at him, which he feels as if kicked, waking him up with surprise. Ondine curses him, stating, "You swore faithfulness to me with every waking breath, and I accepted your oath. So be it. As long as you are awake, you shall have your breath, but should you ever fall asleep, then that breath will be taken from you and you will die!"

That's amazing and horrifying at the same time.
