'They can find their way home, or drive your car etc, without you having to think about driving or where to go, you just zone out and before you realize it you are home.' Every weekend I do a 12 mile walk, mostly rural roadside with little traffic. At one crossing point, a week ago, a couple in a vehicle stopped me and asked if I realized that I had just wandered across the road without looking and they had almost run me other. I explained that I was totally oblivious, had not heard their vehicle approaching and thanked them for them their concern. Today, halfway across the road, I just realized that I was doing the exact same thing at more or less the exact same point. I wonder now if my subconscious is trying to kill me?
