I think the only thing stopping these things from being equally real is our beliefs. The dream is as real as reality. Whether you recreate an experience through intense visualization and concentration OR in real life, its almost the same but your beliefs will decide how much importance/significance you want to give the imagined one. The only thing real is consciousness itself on which all these states are projected and we are the consciousness, not the waking, sleeping, imagining or dreaming states. Everything is equally real and significant.
