Was Banquo's ghost real or just a guilty conscious? During the banquet macbeth saw banquo's ghost.

I would say that
the ghost is real. Why? Two reasons. First, because the presence ofin the play already lets us
know that the play will include supernatural elements. Second, the stage directions call for the
ghost to actually be there, and so the audience would see the ghost too.
Now, is that
certain? No. It could still be a guilty conscience, but that's why I think it is real. People
are haunted privately in some traditions, due to their guilt, and that's what I think happened
here.
