To awaken someone is to wake them up. You might awaken your roommate accidentally by practicing your tap dance routine in the kitchen.
You can awaken another person, and a noise or the smell of pancakes or a scary dream can all awaken you from a deep sleep. You can also use the verb awaken to describe what happens when you wake from sleep: "I awaken every morning with my pillow on the floor." A more figurative way to awaken is to arouse a certain feeling or awareness. For example, a sad movie can awaken melancholy feelings in the most cheerful person.
