‘Going to bed with a dictionary’ immediately conjures to mind an obscure radio interview or perhaps Desert Island Discs, in which some celebrity or egg-head of sparkling wit and inexhaustible vocabulary also admits to reading several daily newspapers and a least one obscure novel, translated from the Russian, a month.In my case, however, the term, ‘going to bed with a dictionary’ means something quite different. 
My computer is upstairs in my bedroom and often, in a spirit of laziness I leave my bed unmade, pulling the covers over when I go to bed that night. In the middle of the night, I stretch out my hand and encounter something with spiky pages, hard and unyielding … my dictionary that I have forgotten to put away. (Indeed, I might as well as said, a thesaurus except this sounds more like some prehistoric animal.)
Not exactly the answer to my dreams.
