I need help with Hamlet by shakespeare!!!?

It's been a year since I took a Shakespeare course but from what I remember, the play that Hamlet uses "Prick the Conscience of a King" mirrors what is going on in Hamlet's world. Hamlet's uncle killed his father and I think something along the same lines happens in the play within a play. If you think about watching the play in person. We are the audience watching the characters of the play as an audience to the play "Prick the Conscience of a King". Maybe that might get the wheels turning in you head. Good Luck!
