Michael Chabon, in New York Review of Books, writes on why he hates dreams:

Dreams are the Sea Monkeys of consciousness: in the back pages of sleep they promise us teeming submarine palaces but leave us, on waking, with a hermetic residue of freeze-dried dust. The wisdom of dreams is a fortune on paper that you can’t cash out, an oasis of shimmering water that turns, when you wake up, to a mouthful of sand. I hate them for their absurdities and deferrals, their endlessly broken promise to amount to something, by and by. I hate them for the way they ransack memory, jumbling treasure and trash. I hate them for their tedium, how they drag on, peter out, wander off…Dreams are effluvia, bodily information, to be shared only with intimates and doctors. 

Fun musings, but I think Chabon should dream more.
