I just had a flashback to a horrible sequence in a dream I had in the early hours of yesterday.
It was part of a longer and fragmentary series, broken up by brief awakenings, sips of water etc. It was already light.
Some parts of the dream had been benign; I remember turning over, pleasantly drowsy to enjoy the next installment, as it were.
I was engaged in a friendly discussion with a young man who was explaining that we were distantly related. For some reason, this seemed important and even delightful.
We were on the pavement and a car was parked alongside. It was twilight or dark. The interior light was on in the car but the windows were opaque, perhaps steamed up. I knew that an older, married couple were in the car but I could not see them. I think they were also relatives, parents of someone close. These categories are as vague and shifting in dreams as they are to dementia patients.
Without warning, my new relation gave a roar of anger and launched himself at the car. Ordinary logic was suspended as he thrust his fist into the vehicle via the air-inlet under the windscreen. His whole body entered the car this strange way, though there was also the sound of breaking glass, as if he had gone though the windscreen itself.
There was no doubt about his murderous intentions. Blows inside the car were so violent that it rocked and moved several inches away from the kerb.
My hand rested a moment on the door handle then I shamefully sidled away to my own car, parked a few yards away. This was also illuminated from within. My initial goal seemed to be reach a phone within the car and summon help but the wisdom of getting into a car made me hesitate.
The sequence ended lamely with me dialling for help, instead, on my mobile phone.
It is hard to convey the full horror of this episode: the mood swing, the loud but obscure violence and the wimpish response.
