"your sleep cycle is like your bodies natural alarm clock. It lets your mind and body know when to wake up and when to start feeling tired at night. Usually, this is based on whether it's dark outside or light in the morning, and how tired you're feeling."
"The sleep cycle is like a paradox of complex motions and deep tranquility entwined in one simultanous action. "
