dO YOUR DREAMTELLYOU ANYTING?

 tHE view that “dreams are the activity of the mind during sleep,” and associated talk of DREAMING as involving various mental acts, such as remembering, imagining, judging, thinking, and reasoning. 

Malcolm argued that such dream-talk, whether it be part of commonsense reflection on dreaming (How long do dreams last?; Can you work out problems in your dreams?) or a contribution to more systematic empirical research on dreaming, was a confusion arising from the failure to attend to the proper “logic” of our ordinary talk about dreaming. 

Malcolm’s central point was that there was no way to verify any given claim about such mental activity occurring while one was asleep, because the commonsense criteria for the application of such concepts were incompatible with saying that a person was asleep or dreaming. And because there was no way to tell whether various attributions of mental states to a sleeping person were correct, such attributions were meaningless. These claims not only could be made without an appeal to any empirical details about dreaming or SLEEP, but implied that the whole enterprise of investigating dreaming empirically itself represented some sort of logical muddle.
