It was Hamlet's funeral for he had died. Horatio stood over his dead friend's corpse, crying while Fortinbras stood there stoically in silent having nothing to say.
Then, all of sudden, Hamlet's body began to convulse and twitch. Hamlet's eyes woke up, and then Hamlet laid up. Hamlet then also woke up and looked at his friend.
"Horatio! I hath returned from the dead, and thou lives again!" Hamlet yelled.
Horatio continued to cry.
"Horatio! Are thou not entertained by my return to life!?" Hamlet yelled.
Horatio cried more, "You were to die, Hamlet!"
Hamlet was sad and got out of his casket and walked away, inadvertently ruining a state funeral, and as punishment was sent to the dungeon.
