Dream of

I dreamed my friend and i were driving in his white works van, we were headed somewhere local and i was sat in the passenger side whilst my friend Mark, went to the back of the van to fetch something from a box.As he did, the van carried on moving toward the junction, I looked back to see if my friend was on his way back to take his place in the driver seat, when I actually saw us travel over the white give way lines, over the road and into a large expanse of water.The van tipped forward into the deep water, i felt no fear, slight bewilderment, the thought to unlock my door passed through my head and i realised it would be jammed by the water, it was up to my neck, the leather black seat engulfed me pushing me forward to my knees, i really thought i was about to die and experience drowning when I awoke with a gasp of air in terror and relief .
