How do you see places in your dreams that you have never been to?

Basically, your dreams are controlled by your brain. If you think about being at that place as the last thing you think before you go to sleep, you may be able to dream about the place. Even if you've never been there! BEWARE! The dream may not look nothing like the actual place. It will look like your interpretation of it!

Dreams are generated by the subconscious (unconscious) mind, which does not often respond to the wishes of the conscious (waking) mind. So it is quite difficult to order up a specific dream one wishes to have. Also, dreams have no magical powers or access to information beyond the dreamer's own mind. So if one has no memories or knowledge of places, one would not gain accurate information from dreams. Any dreams of such places would be fantasy, not based on facts.
