I had a paranormal experience that I shared on this site 5 or 6 years ago (I think the title was "The Thing By The Shed). I was cleaning up around my storage shed and bent over to pick something up when I saw something that looked like a stick laying on a cement pad. I didn't look directly at it but when I reached down whatever this thing was popped into an arc-like shape and made a cracking sound at the same time. Then it seemed to jump under the storage shed, which is on piers. I was like WTH just happened? I ran to get a flashlight but when I returned I didn't see anything under the shed. To this day I have no clue whatsoever as to what that was. But after that nothing strange happened at my house until 2 years ago.
We had a large covered swing we had bought from Lowe's in our yard and one day I was walking towards the swing when it started swinging very hard all by itself. It swung about 3 times and stopped. For some reason I pretended that nothing had happened as I walked by. I don't know if I ignored it thinking that I didn't want whatever it was that caused it to swing to know that I was acknowledging it or if I just wasn't surprised after the first experience several years earlier. Anyway, nothing else happened until several months later. One day I was walking towards the swing and it did the EXACT same thing! Again I pretended not to notice but inside I was pretty stoked! I'm hoping it was the spirit of my elderly neighbor who I was close to that had passed away about 10 years ago. I feel like she was letting me know that she was watching over us. If it wasn't her then I'm thinking maybe it was another spirit that was just passing through. I don't know...
But what does worry me sometimes is that we buy a lot of antique and vintage items and figure one day we will buy something with a Spirit attached to it.
The original submission you mentioned was titled "The Thing By My Shed." Here's the link for anyone interested: https://www.yourghoststories.com/real-ghost-story.php?story=24023
While it is possible that random breezes could be responsible for *starting* the swing moving, they definitely wouldn't account for the fact that the swing abruptly stopped. Did your elderly neighbor sit in the swing when visiting you, or is this piece of furniture a more recent acquisition? As the repetition of the event was several months after the first experience, I'd suggest that it is not merely a transient spirit "that was just passing through" but something/someone with a vested interest in you or in your property.
