Go where? The spiritual is what it's all about. That was even true of Jesus' parables.
Though there is symbolism in the book of Revelation, but not all information should be interpreted as such. The correct way to read Revelation is that, if the plain literal sense makes good sense, then don't seek any other sense. One of the major problems that expositors make, is that they symbolize what is meant literal.
Regarding Jesus' parables, not everything that Jesus said is a parable. And He told us why and to whom He spoke parables to:
========================================================================================
Then the disciples came to Jesus and asked, “Why do You speak to the people in parables?”
He replied, “
The knowledge of the mysteries of the kingdom of heaven has been given to you, but not to them. Whoever has will be given more, and he will have an abundance. Whoever does not have, even what he has will be taken away from him. This is why I speak to them in parables:
‘Though seeing, they do not see;
though hearing, they do not hear or understand.’
In them the prophecy of Isaiah is fulfilled:
‘You will be ever hearing but never understanding;
you will be ever seeing but never perceiving.
For this people’s heart has grown callous;
they hardly hear with their ears,
and they have closed their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts,
and turn, and I would heal them.’
But blessed are your eyes because they see, and your ears because they hear. For truly I tell you, many prophets and righteous men longed to see what you see but did not see it, and to hear what you hear but did not hear it.

"The knowledge of the mysteries of the kingdom of heaven has been given to you, but not to them"
The 'You' in the verse above are the disciples as well as all who are in Christ. So, we have been given the ability to know the mysteries of things contained in God's word.
The 'them' is that generation of Israel to whom Jesus spoke the parables to. As the Lord said, He spoke in parables to them in fulfillment of the prophecy of Isaiah.
Many attempt to use this scripture to infer that we has believers in Christ cannot know what the book of Revelation is saying because it is all symbolic, which is a lie! It is those who claim that it is symbolic who don't understand what it is saying.
God gave us the book of Revelation for the following reason:
"The revelation from Jesus Christ, which God gave him to show his servants
what must soon take place. He made it known by sending his angel to his servant John
The book of Revelation then, is information about what is going to take place in the future which are the events of God's wrath and all related information, which will be carried out via the seals, trumpets and bowl judgments, as well as the plagues that the two witnesses bring upon the earth. These plagues of wrath will all take place upon the earth literally. If these events were all symbolic and we couldn't know what they mean, then God would be failing at showing His servants the things which must soon take place.
Preterism and Amillennialism, are two of the most destructive false teachings out there.
