Ugh, I do overnight duty, and I sometimes get so spooked around here! I spend the first two hours monitoring my ct. from the kitchen via baby monitor, before turning her and putting on the bipap (she gets weighted as part of her PT for the first two hours w/o bipap, so I don't have to be in there personally.) This house is huge, modern, with all hardwood floors. There are large windows without coverings everywhere, so it would be easy for people to peek in. This house has been making loud settling noises with the changing of the seasons, and sometimes it sounds like tables are slamming in the next room! I'm assuming the floor planks are doing that. I'm no believer in the supernatural, but sometimes it sure is creepy in the wee hours of the night!
