In Act 1 Scene 4 Hamlet, Horatio and Marcellus were waiting for a ghost (who was Hamlets dad), while they were doing that they looked over to the Kings palace and saw that Hamlets uncle the king was drunk once again, hamlet was mad. The ghost then showed up and Hamlet was wondering if it was a friendly ghost or evil spirits sent from hell. Then Horatio and Marcellus warn Hamlet to not go with the ghost as they think it is an evil spirit, which will do terrible things to him and make him go crazy. Hamlet then ignores Horatio and Marcellus and then the ghost takes Hamlet to have a private conversation.
