If they are, then they’re going in the wrong direction for half the year.
The rugs are almost certainly made from an artificial fabric and there may not be much friction between them and the likely artificial fabric of your fitted carpet. Perhaps turn one of your rugs around to see if it still moves in the same direction. If it does (most likely) then it must some property of the fitted carpet that seems to create more friction in one particular direction.
My other WAG: somebody in your house is screwing with you. Claim to each house member that you are turning one of the rugs around (pick a different rug for each person) but don’t actually do it. Whoever it is may be tempted to move it in the opposite direction - then you will know.
I still think it’s ghosts.
I’m wondering if the floor in here is not quite level - not enough to actually see/feel, but juuuust enough for this stuff to migrate in the same direction.
Might there be someone other than you who is walking upon the carpets?
Not really. My husband will come in occasionally but that’s a couple times a week, while I am in there almost every day, and go in and out multiple times.
Obvious question - do you have pets?
Did anyone ever die in that room?
Nope.
The rugs are trying to get to the closet to hang out with the extra wire coat hangers.
Consider affixing (somehow) Velcro to the carpet and the underside of the rugs. Seeing as how even nails were not strong enough to hold these carpets in place, I would expect you would need large areas of Velcro (like, the entire underside of the rugs) and not just little patches.
If all else fails, there’s Gorilla Glue.
I tried the self-adhesive Velcro. Didn’t work very well.
Maybe I should check underneath for missing socks.
I’ve come to this conclusion independently while trying to figure out the runner in the upstairs hallway. The underlying carpet has approximately vertical yarns that I think were probably folded over in a zigzag during manufacturing but then mown off just under the bends, or something like that. The yarns look like grass. But they’re not vertical on average, they have a bit of a lean. Perhaps they were stitched in by a process moving that direction in the first place, or something like that.
Was your house built over any kind of ancient burial ground? I don’t want to belabor the point, but all of the conventional explanations have failed, not one of them addresses the round rug moving on it’s own, so I do believe we have to examine other-worldly explanations also. Plus, it’s easy to just blame ghosts and stop wondering about it.
A racetrack???
Shouldn’t have bought a magic carpet from that genie.
Mimics. They’re positioning themselves so that when they attack you’ll be in the most advantageous position for themselves and the least for you.
I use heavy stiffer backed rugs and they tend not to move. I also try to place rugs where furniture wil be sitting on at least part of it.
NO KILL I
Well, it likes you more than me.
