" This bodes some strange eruption to our state." This is the line that tells that something will happen in the play. Horatio, after seeing the ghost of the dead king, forecasts that something bad will happen in their country.
These lines are not right:
-Such was the very armour he had on. Horation notices the ghost is wearing the king's clothes.
-He smote the sledded Polacks on the ice. Horatio refers to attitudes the King had when he fought in the Pole.
-With martial stalk hath he gone by our watch. Marcellus describes what the ghost does: to follow them every night.
