Just outside of Houston, TX is Newport Subdivision. When the subdivision was still relatively new and construction had just begun, multiple families chose to build homes under contract along the streets. All was well in the seeming idyllic neighborhood for these new homeowners for quite sometime, until they began to notice strange rectangular indentations in their yards and odd things began to happen around some of their homes. There was no explanation, until a man appeared at a home in the neighborhood that was planning to build a swimming pool. He claimed that the neighborhood had not been built on vacant land, but had in fact been built on a cemetery.
