Awake/Awakening
Throughout the movie, the concept of becoming "awake" or "waking up" is also prevalent. In the dictionary there are many definitions for the word "awake." They include:
"To rouse from sleep." Morpheus and his crew wake Neo up in the matrix pod.
"To emerge from sleep."
"To become conscious or aware of something." Once Neo physically awakens and is taken out of the matrix, his mind then becomes aware of what the matrix is--he gains knowledge.
By the way, the word "awakening" (a form of the word "awake") is often times used in reference to "a renewal of interest in religion." This definition is particularly significant because of all the religious symbolism in this movie.
