I friend of mine has a lady called Rose living in their house (they settled on that name after getting a strong smell of roses)
99% of the time,she's fine-the kids have said she tucks them in if they lose their bedcovers in the night or she'll stroke their hair if they are ill
My friend said he was ill one night and felt her take his temperature and his wife often feels someone touching her hair/cheek
If they lose something,they ask her and it appears almost immediately
I've seen her move a crisp packet across the arm of the sofa (the dog reacted by walking over to her and offered his paw, the cat fucked off out!)
I also saw her slide a mug across the table
However,if they do something she doesn't like,God help the family
They once redecorated the kitchen and she threw a box of christmas decorations at my friends head and she took a China figure (that had been sat on a bookcase in the lounge) and put it on the top of the clock (that was in the kitchen) when they bought a new sofa
She was really annoyed when they had to replace the front door and windows so caused endless problems with the fittings (two panes of glass shattered for no reason and the front door refused to lock properly)
They get around it by explaining what they are going to do and if she doesn't like it,they will change it immediately
Seems to work as long as she knows about it first,she's fine with it and accepts that the new 'thing' is ok as its both their homes
I wouldn't have believed it if I hadn't seen it with my own eyes
