I dreamt I was driving along in a car with two men (no idea who they were)and my youngest son. It started off a beautiful sunshiny morning. But then the sky darkened, not just with cloud cover but like night. We stopped the car and as we looked up there seemed to be a sort of channel - river-like forming in the clouds with a reddish hue. If you can imagine the effect of a slightly different fluid being jetted across water so that you have swirling edges at the junction of the two fluids, that is what it looked like. It seemed to divide the clouds, but the sky on the other side was night, not day as it had been earlier. It was a bit like looking through to a picture of a red swirling nebula. I felt a mixture of fear and excitement in the dream, with no idea whether this was a beginning or an end, a good or bad thing. I decided we might be safer in the car and got us all back in. The sky seemed to clear and the strange effect to disappear. All very odd.
