Maybe the dreams are the real world, and this is just a collective attempt to establish order.
Out of all the possible universes to exist, wouldn't it make more sense for our universe to lack any concrete rules or order? We dream and try to impart our will, to impose consistency, and that dream is our universe.
That's why this world still sucks so much, because it's coming from a place of chaos, a place with no real rules.
The only reason our "dreams" often seem based on real life is because this dream influences our real lives.
Do you get what I mean, man?
