Some years ago now, I was startled from sleep by a very vivid impression. A loud, crashing chord, and a sudden powerful image – as it happened, a head-and-shoulders of a pale-faced young man standing in front of a tall (it must have been, I couldn’t see the top of it), neatly clipped beech hedge in very bright sunshine. I didn’t know him. But the crashing chord was so loud and the image so sudden, bright and insistent, that it startled me awake.
A few years after that I was travelling to London on the train when again a sudden, loud, crashing chord sounded in my head, and some memorable words about my life in the future (yet to be tested, it related to old age) came in to my mind.
Then last night, at twenty past four, I was startled out of sleep by the most tremendous, rending, tearing crash – like someone dropped a skip onto the road from a height. It was cataclysmic, apocalyptically loud. Eventually I got up and went to look around the house, fearful in case something dreadful had happened. All calm and peaceful; just inside my own head.
What is this? Is it a neurological phenomenon?
