Dream

Dreams are not just product of one's mind, it's a connection between selfs, meaning that when someone is dreaming they are connected to another version of themselves. They share the moment, but not the memories, that's why in dreams one is not in control of the flux. When someone experiments lucid dreaming, it is usualy caused by a connection to a universe with very relaxed rules and where the subjects are prone to be controled by those dream connections. Those connections exists because a contience is a global phenomena, every single version of a mind can have differenct lives and memories, but the process that made one, oneself is commom, is a product of the multiverse and therefore is unique, existing at many places at once.
