I see you

I've been watching Titanic on replay for a couple of days now and I realised the point James Cameron was trying to bring across: I see you.
In Avatar it's quite obvious, cause the I see you moment is kind of emotional and stuff, plus the main theme song is titled I See You.
Well, in Titanic Jack tells Rose he sees her and in My Heart Will Go On, Celine sings, "Every night in my dreams I see you".I
 don't know any of his other work, or maybe I do but unknowingly but I hope he got his point across now cause....how many years were between Titanic and Avatar? And he's still going on about the same thing, in exactly the same wording?
