I think that maybe there is a universal state of infinites posibilities where all elemental particles are mixed together in chaos, and is the conscious who puts order in this chaos thus forming the material reality that everyone of us experiment everyday. I have reached that thoughs by reading about Quantum Physics. Maybe, a dream is just a travel of the conscious in this world of posibilities not limited by time and space.
