Ghost: I could a tale unfold whose lightest word Would harrow up thy soul, freeze thy young blood,
Make thy two eyes, like stars, start from their spheres,
Thy knotted and combined locks to part,
And each particular hair to stand an end ...

This is from William Shakespeare's play Hamlet. The Ghost speaking is the ghost of prince Hamlet's father. I don't know what the question you got was but, in this section his ghost dad is telling Hamlet his story is sooo terrifying that it would make his eyes pop out of his head, "harrow" or scare/haunt him to his soul and make his hair stand up (like when you get goosebumps.) And the story is that Hamlet's Uncle Claudius killed Hamlet's father  because Uncle Claudius wanted to be the King. AND then he married Hamlet's mom Gertrude too. AND she was in on it the whole time!
