In hamlet act 3 scene 2 - how does the play either dramatize a particular conflict or heighten it

In this scene Hamlet confronts Claudius with the murder of his father through the play he's presenting to the court, this heightens the conflict between the two men....... In the same scene we're also reunited with a "sane" Hamlet..... something I believe dramatizes the conflict because he's been successful in duping those around him. Proof of this comes in his coversation with Horatio (completely sane and coherent), and then a complete change when the King and Queen arrive...... his pretension in now totally obvious.
