Let me tell you a story. I drove a car about 5 hours at night and began to fall a sleep. Eyes grew harder and harder and I decided to sleep few hours. I stopped at small parking place near the road. I was so tired and fell asleep next minute. But some sound woke me up, it was knocking sound. Someone knocked at the window. I looked around in the dark, nobody here. "Just a dream", I said and lay down. Few second after I've closed my eyes , someone knocked again, this time it was match louder. I opened my eyes. Nobody again. I got scared... a lot. I've locked doors and drove out the parking place. Not fast, I drove slowly, and looked back trying to see who was there. About a minute after I saw something terrible behind. A huge truck pulled of the road and crashed around my parking site. The driver fell asleep. Strange feeling swept over me, some mystic mix of fear and joy. What was it?
