I would say this happens to me as well, but I will set something down, knowing exactly where I left it, and come back it's nowhere to be found. Even if I'm the only one home.
Or like, if I drop the remote off the bed, and I find it an hour later, 30 feet away, in another room. Like, how the hell did that happen?
I think it's a ghost. Not really, but I have nothing else to go on.
