My gf's house was like this. the first time I brought my dog there he just stared at the staircase, on the landing like someone was standing there... and growled, and she said her dog, before she came home and found him dead, used to stare at teh same exact spot and growl. we came down stairs one morning and she has two shelves that run from floor to ceiling, with about 50 Buddhas on them, and every one was turned facing the wall in exactly the same way, like down to the millimeter.
she had a monitor for her daughters room, and she used to be woken up by all sorts of fucked up noises, like screaming... on the monitor, run into her daughter's room, and it would be quiet as a mouse, but the mobiles hanging from her ceiling were all moving around like someone whacked them hard and there's like 10 of them.
she woke up one night from a nightmare and she SWEARS that written in blood (or something) across her bedroom ceiling was...."Don't worry, I'm OK.....Beth stre....."
she did some investigation years ago when this shit first started happening, nothing ever happened in her home, .
But when she was looking at different units in the development to buy 9 years ago, and she went into one of them and immediately felt a presence and practically ran out, my girl is a very metaphysical like that, and she doesn't forget anything... so she investigated that units history and some girl named beth killed herself in it. i shit you not. She thinks the girl's spirit followed her from that house because she liked her or some shit
