With a cry similar to a rooster's you cast the spell. For a moment you feel as if you had just awakened from a confortable nap, but as the feeling fades, those around you begin to stir.

All sleeping creatures in the affected area awaken. Those who are unconscious because of nonlethal damage wake up and are staggered. This spell does not affect dying creatures.
