Enter the Ghost of CAESAR BRUTUS
Ha! who comes here?
I think it is the weakness of mine eyes
That shapes this monstrous apparition.
It comes upon me. Art thou any thing?
Art thou some god, some angel, or some devil,
That makest my blood cold and my hair to stare?
Speak to me what thou art.

GHOST
Thy evil spirit, Brutus.

BRUTUS
Why comest thou?

GHOST
To tell thee thou shalt see me at Philippi.

BRUTUS
Well; then I shall see thee again?

GHOST
Ay, at Philippi.

BRUTUS
Why, I will see thee at Philippi, then.

Exit Ghost

Why might Shakespeare have included the ghost of Caesar?
