Weird dreams

I had a great long dream last night. I do not know if the dream was trying to tell me something or was based upon my own thinking.
I was driving along a dual carriageway road. I could see for miles and miles ahead. There was no oncoming traffic but there were quite few cars ahead of me. We seemed to be all travelling at the same speed as the gap between cars did not shorten or get longer.
Along the road were traffic lights. Mostly they were green; the red lights there were seemed to have no pattern of dispersal compared to the green. After a while, I noticed that if a car was stopped by a red light, it disappeared. I don't remember seeing exactly what happened. There were side roads at the traffic light but I do not remember seeing any car turn off up one of these.
I had no sense of panic or fear. It did not really bother me that they went out of my sight; I seemed to accept that a red light just caused them to disappear. I did not worry about my getting stopped at a traffic light.
The obvious explanation of this does not take any degree in parapsychology or, indeed, any -ology. But I cannot see why this was being revealed to me at this time. I am free of my old mate The Black Dog; have been now for longer than I can ever remember. I am not conscious of death looming large in my mind other than the Dignitas debate recently. And, of course, Christmas was the time of my mother's death. If it was that, why nothing in the 25 years since that occurred? There was nothing in the DIY suicide that might have brought this dream about.

Bloody Grandma Edwards!
