Filmed in Ljubljana, March 1st at 12:44 in the morning. We seem to have what sounds like a very loud “sky dragon”. See here. The witness claims to have never heard this before. This is definitely not an overlay.
Is it a factory valve as is the explained source of many of these types of sounds? It’s very atmospheric and has a nice echo. At one point we see a neighbor in a window or doorway. He seems to be talking to another witness curious about the sound. One problem I have in assessing this video is that I don’t speak the language so I can’t judge their sincerity or comments.
There seems to be an urgency to the noise at certain points like someone pushing a button over and over and not waiting long enough for a regular blast. This irregular blast seems manmade like someone is controlling it. It really doesn’t sound like the Malaysia or Oshawa sky noise but it IS similar.
UPDATE: Great! I found a twin video from Slovenia below. See the definition of a twin here. A “twin” is a video filmed at the same time in the same location by different people. This is proof it’s real. And also in this one it sounds like Oshawa, Malaysia and Sweden. See Oshawa here. I find “sky dragons” to be the most interesting sound of all. See a lesson in types if you don’t know what that is here.
Since this is the fourth incident of “sky dragons” I think we can safely assume this type of sky noise is real and not factory valves. They sound similar depending on the distance they’re filmed. We have Oshawa, Malaysia, Sweden and Slovenia now. None of these have been explained except Malaysia. Malaysia’s government put forth a lame explanation about a palm factory valve which was strongly refuted by commenters in the news article here. So the question now is, it’s real but what is it!
plus: sounds genuine, person has no related posts on YT, very clear recording that sounds atmospheric, other witnesses
minus: suspicious search tags, cliche title with date, sound seems controlled by someone
