I vaguely recall seeing a particular scene from a movie or possibly a trailer. A man enters a room where a woman is painting portraits of him. She explains to him that even though she has never met him before, she consistently sees this man in her dreams. I believe the implication is that she and this man were once close, but that she has somehow lost her memory of him. Nevertheless, she retains some subconscious memory of him that seems to manifest itself in her dreams. I do not recall if he is aware of who she is on the other hand.
I want to say I saw this clip in the mid-2000's or so. That's about all of the details I can scrounge up. I don't remember the actor or actress involved in the scene.
