After seeing "The Philadelphia Experiment" I had a disturbing nightmare. There was a huge,multi-car pile up on the main highway out of my home town. They decided to simply pave over the bodies instead of cleaning it up....so there were arms and legs sticking out of the road. That one gave me cold chills.
That reminds me of the urban legend regarding the Manila Film Center where people were buried under wet concrete in order to get the building completed on time by order of Ferdinand Marcos and Mrs Shoes.
