I had it happen earlier this year, for the first time, ever, and it felt,
well, weird.

I think I did the right thing, but it's hard to say. That funny little
voice in my head just kept saying "stay on the ground..." -- so I did.

Never heard that voice before.

Yes I have and he was a CFI, I ended up telling to get out of the
airplane and that I would not fly with him. I also reported him to his CP.
