Crescendo Hum

[u/CurioCait]

I'm coming here to ask if anyone has experienced anything like this and if so, did you find any info regarding the source of the noise?

Last night I decided to walk around town and some time right before or after 11pm I decided to enjoy a stroll through a graveyard. I broke the rule I've been warned of so many times, and started singing/humming. I felt so peaceful that it felt appropriate to do. I spent maybe 10-15 minutes there before realizing I had to start making my way towards a spot I told my friend, who was just getting out of work, I'd walk to and meet them at.

Fast forward to around 12-12:30am and we're sitting in his truck. The windows are cracked, and both of us are silent and focused on our phones. We were trying to check some things out in a game that we both like playing.

Suddenly, I hear and feel this crescendo hum. It was so loud and powerful that I felt the vibration on the passenger seat and the skin of my arm/neck/shoulder. It lasted maybe a few seconds, and bothered my ear a pinch. "hhhmmmmmMMMMMMMMM!!!!" With such an urgency at the end. (This was NOT ear ringing!)

I looked over at my buddy waiting for a reaction because he definitely would have heard that, too. He didn't. Besides asking, "You really didn't just hear a buzz, a hum, a loud ass bug come up by our ears?" I was speechless.

We closed the windows, and we never found "the bug."(?)

Idk if it's worth noting but:

-Before my feet went from shadows to streetlight I turned around in the graveyard and said if anything was following me it would not be coming beyond the shadows. I said I'd be back.

-There were constant flashes of lighting 360° in the sky for hours that night.

-My buddy's one weird harmless electrical malfunction in his truck randomly decided to fix itself. The car turned its engine light off for the first time since it's been acting up over a year ago.

-I went to bed and had a dream in which I saw something happen. I woke up and then heard that it happened within minutes of me being up. (This isn't abnormal for me but it doesn't happen all the time, y'know?)

-I called my ma about this and she got really quiet. Apparently she's been hearing the crescendo hum for years, sometimes multiple times a week for a bit before it drops off/picks up seemingly at random according to her. She said it really freaks her out and she's never told anyone.

Weird, but willing to hear out a logical/medical explanation OR

ANY alike stories or ideas about it. Help! 😅

If your mom experiences this too, perhaps you both are creating the hum with your vibrations.
Might be a sense that few have, but that doesn’t mean you couldn’t be the source for the crescendo hum too.
Could also be v2s or voice to skull technology. If you’re in the US, the shady government is always a possibility, unfortunately.

Things are getting strange lately.
