Holy fuck. This sounds exactly like what happened to me a year ago. One day, it came out of nowhere and I thought I was having a stroke. I was too dizzy to do anything and thought I might actually be dying.
After a month, it got a lot better but I still constantly get bouts of it, especially when I bend over. It makes playing with my kids incredibly difficult at times.
If it turns out I have BPPV and my doctors didn’t think to test me for THE MOST COMMON CAUSE of vertigo, ima be… unsurprised 😅
