The Ghost Quotes in Hamlet

What may this mean, / That thou, dead corse, again in complete steel, / Revisit’st thus the glimpses of the moon, / Making night hideous, and we fools of nature / So horridly to shake our disposition / With thoughts beyond the reaches of our souls?

O Hamlet, what a falling off was there, / From me, whose love was of that dignity / That it went hand in hand even with the vow / I made to her in marriage; and to decline / Upon a wretch whose natural gifts were poor / To those of mine.

Upon my secure hour thy uncle stole / With juice of cursed hebenon in a vial, / And in the porches of my ears did pour / The leperous distilment,

In the same figure, like the King that's dead.
