In 2020, the author Michael Rosen was admitted to hospital with Covid-19 and spent 40 days in an induced coma. In the aftermath, he had a strange and vivid dream: he was at Land’s End in Cornwall at the edge of a perilous cliff. He tried to squeeze through a hole in a wall to get to safety but got stuck.
“Immediately after the dream, I can remember feeling first that it was so real, that I had ‘been there’ on the cliff and my wife, Emma, helped me. It really felt like it had happened,” Rosen recalls. “This has stayed with me. I sometimes catch myself thinking that there really was a time when I was stuck on the top of a cliff on the wrong side of a dry-stone wall with the sea hundreds of feet below, and that there was a hole through which I could escape that Emma was pushing me through.”
