Everybody had a dream at least once in his life, it's so real as match as the “real” world even if sometimes it breaks some rules some physics rules you can fly sometimes you can do extraordinary things still you accept it as if you are in the real world, You make your own world you see people you know or not, buildings, trees, seas the world you're living in your dream it's pure imagination but it's true in its context, your world in the dream is just where you are what you see and what you sense there is no other towns no other places you create your world as long as you walk .
Everybody in this world is living a dream! It's so real we accept it as the real world with its physics rules it's more stable than the dream BUT... I believe in the other world where we all people are making a dream where the dream is the second state of dreaming
