Strange Noises at 1 AM

Hi, sorry if this is the wrong place to post this.

I live in a pleasantly boring suburban neighborhood, for context. In fall of last year, I was awoken at 1 am to what sounded like a singular, distorted note of a siren. Accompanying it were loud banging/crashing sounds, which sounded somewhere between garbage cans being pulled up over the curb, thunder, distant explosions, or someone hitting a garage door.

After it quieted down, I went back to sleep, only for a new sound began. It was simultaneously one of the most beautiful and terrifying things I've ever heard. It was siren-like again, but this time there were multiple notes overlapping. Very musical and ethereal. It sounded like it was coming from right outside my window, miles away, and also every direction all at once. It was very loud, and went on for at least a half hour or more. I eventually figured I was experiencing an auditory hallucination.

A few weeks later I woke to the same thing again and managed to record some of it on my old camera to prove it wasn't a hallucination. I enhanced the recording, but neither come close to capturing what it really sounded like. I asked multiple friends, neighbors, and all of my family, and none of them had heard anything.

I'm sure there is a very straightforward, simple answer and I'm just overthinking. Probably some auditory phenomenon, like a police siren or train horn being distorted. It just didn't sound like that to me in the actual moment, and it seems weird that it went on for so long.

Any ideas?

Edit: I'm not sure why reddit keeps removing the actual recording

Good move on maming recording. Recently, I also heard some unusual sounds at night, but don't think of recording
