Dark rides

When I was younger I always had this dream. I wouldn't dream it every night but every so often as I drift to sleep it crept into my brain and played itself out. It started in the parking lot of Shoppers in Potomac Yards. It began with one all black Escalade with dark tinted windows. Suddenly I would appear and it would follow me. In my dream I'd begin by walking briskly and turning corners and taking lighted roads I knew. But, as the dream went on more and more all black Escalades with dark tinted windows would appear and follow me. I would run through cities and passed people I knew but no one seemed to notice my dilemma. Finally, I'd run through the woods and come to an edge; below it nothing but darkness. I'd stop with the tips of my toes slightly over edge and the trucks would come zooming my way... And that's where my dream would end and I'd wake up afraid and panting.
