No, dreams are sometimes considered a form of normal hallicination. While dreaming, our memory and other cognitive functions vary, and it is possible that these also trigger mentations that we call dreams. The physiological basis of spantaneous sources (which I call hallucinations ), may be differences in oxygen, blood supply, other nutrients or even abberant electrical / chemical stimuli. These are not constant, and even ill hallucinations change according to influence of surrounding sensory stimuli. Whatever the sources of these dreams / mentations are, is not yet scientifically pinned down to one exact occurrence. Dead brain tissue is not an option since it does not "work" by definition. It may not even be something we know yet to exist physiologically. OBEs testify to an extra-corporeal possibility. As a scientific being I have to keep this in consideration. The borders between healthy and ill hallucinations are vague if we consider them to be some form of spontaneous stimuli that illicit further cognition. But this is how far I can clarify the terms for myself. It will be interesting to see more opinions.
