“Why don't we dream when we are awake?". I would suggest that being 'awake' is when we dream best and continuously. Assuming the world, external to ourselves, exists, then the only access we have to it is through sense data. This stream of nerve impulses, which passes from our sensory receptors to our brain, cannot be said to represent, nor to be analagous to, those events which occur 'out there'. We can only assume that the brain 'fabricates' an image, of external reality, which serves to allow us to interact with it. It is this process of 'fabrication' that I would suggest is no more, or less, than dreaming. The real question is, "Why do we dream when we are asleep?".
