We were sitting in our great room, all of a sudden we heard very loud popping noises( no not firecrackers although it sounded like firecrackers) and all of a sudden the tiles on our floors started buckling and cracking apart. Very scary....anyone know what that could be???? Poltergeists? We called 911 who said they didn't see cracks in the foundation or a sinkhole. This sucks and I'm really upset. We're at my mother's place now but I want to go home!!!!! Waaaaaaaah!!!!!!
