Morpheus: .."You’re here because you know something. What you know, you cannot explain but you feel it. You felt it your entire life. You don’t know what it is, but it’s there like a splinter in your mind, driving you mad. It is this feeling that has brought you to me. Do you know what i am talking about? 

Neo: ‘The Matrix’

Morpheus: Do you want to know what it is?
