I had a dream last night I was driving along a high way, when I noticed rows of horizontal lines appear in my view, not on the road but in front of me as if floating in the air, I began to slow down, then vertical zig zag lines appeared through them, stamped into them, I instantly put my foot on the break, that is when I saw beyond them, there was someone who had ran out into the road, the cars behind me were sounding their horn, they were furious that I had stopped, I got out the car to see to the person, as did the other drivers coming to yell at me, until they saw why I stopped, they were then reassured I had to, why did the lines appear, surly I would have seen the person, but would I have been able to stop in time? I woke shortly after this, your thoughts?
