Bloody headlights

I dreamt I was driving a car on a dark road and all I could see was a pool of light and the white stripes on the road. The car was full of people and voices I couldn't see either. I was driving down a straight road and going very fast and at some point I thought I might have hit something but the sound left as quickly as it came. I said should I stop?? And a voice told me it's nothing, carry on, and as I drove on I realised that the white stripes of the road had bloody streaks across them, but that's not possible, unless the bloody streaks were on my windshield instead.
