The barn door closes on its own after Sven walks out of barn...not sure what to think.

So I have sat on this video for over a year because it was just too weird to post... Lisa was in the barn with Sven and I was talking to her through the Ring camera because the dogs were digging up something in the yard. I was up at the house so I was hoping that either Grace or Lisa could stop them before a huge hole was dug creating a danger for the horses. Sven walks to the door then though it while at the same time over the Ring I ask Lisa "was something there" meaning was there something in the ground that the dogs were trying to get at. As Sven clears the doorway at 00:29 the door to the barn closes forcibly. Sven did not touch the door, nothing got caught on it as he passed through, there was no wind that day and that door has never closed on its own before. The property we live on has had people living here since 1860 when the house was originally built. For what its worth we have had two friends visit on separate occasions who both stopped at the entrance to the forest refusing to go any further because they got a bad feeling. One said people have died there and one didn't want to go into that space and be "contacted or bothered". They did not know each other and did not know of the others experience. Lots of interesting events have occurred during our ten years here. Just two weeks ago Lisa had a friend of over 50 years come to visit us from Chicago. The day before we got there Lisa found a framed picture of her and her friend Kelley face up on the floor of the bar area. The frame was on the wall, 7 feet off the ground, in amongst 11 or 12 picture frames hanging in the same area. The only frame that fell was the picture of the two of them. The nail was still firmly in the wall, it was face up on the ground, not dented or damaged in any way and the glass was not broken. No damage to the frame that fell 6 feet onto a hard slate floor landing face up... Things that make you go hmmm....
