I see dead pixels

Cole Sear: I see dead pixels.
Malcolm Crowe: In your dreams?
[Cole shakes his head no]
Malcolm Crowe: While you're awake?
[Cole nods]
Malcolm Crowe: Dead pixels like, in graves? In coffins?
Cole Sear: Walking around like regular pixels. They don't see each other. They only see what they want to see. They don't know they're dead.
Malcolm Crowe: How often do you see them?
Cole Sear: All the time.

Lynn Sear: Cole, you're scaring me.
Cole Sear: They scare me too sometimes.
Lynn Sear: They?
Cole Sear: Dead pixels.
