Abstract

I suppose the most obvious difference in fact between dreams and waking life is the chaotic nature of the former. But this somehow seems to be a mere contingency. Some of our dreams are more contingent than others, and it seems hard to impose any upper limit of coherence on them. Also it is usually after we wake up that they seem incoherent. Similarly many dreams are largely matters of sensation and emotion, mood and atmosphere, with little or no reasoning in them; but this again is contingent, and dreams vary; Professor Broad, 56-57) relates a quite detailed scientific experiment which he carried out in a dream.
