Dreams are as if experienced through a single sense which only subsequently self-divides into sight, sound, feeling, thought. In this respect they are in some ways like a movie or novel. Every fictional character, no matter how realistic the world they are placed in is a dream character experiencing a dream. The wall separating them from their creator is porous even if it is pretty much invisible. This is all quite unlike waking experience in which tracks diverse in their source are combined in a posterior act - sight, sound, body feeling, contextual awareness etc. What makes it so real-seeming is the way these conspire. Experience, not a flux of discrete events but a divergent polyphony of infinitely extendable meanings and meta-meanings. Any attempt to impose unity on these is no more than that, an attempt, itself yet one more divergent track. An artificial synthesis imposed by the mind and its latent metaphysical presuppositions. Artificial too the attempts to 'overcome' this.
