This is exactly the thought behind the Hindu philosophy of Advaita (non-dualism). Not only does it argue that our state of consciousness and our state of dream are identical but also posits that in order to switch between them we have a thirst state of deep sleep.

Not only is this the highest state of consciousness but it should also be universal i.e. all of us are the same consciousness.
