Sometimes I sleep with the radio on. Because sometimes, especially when the nights are light, I can’t sleep without it. I find the Shipping Forecast strangely soothing and the faint drone of the World Service in the background wafts me slowly off to sleep. It makes for whacky dreams sometimes – last night there was clearly some programme on about vets who moonlight as plumbers, because I dreamed I was hacking a radiator to pieces in a room slowly filling with kittens. I don‘t do drugs, but I do mainline Radio Four.
