Midway through the ATM transaction, I felt a very distinct pop
in the back of my head--literally
in my brain. Suddenly, my brain felt like it was rolling around in my skull as if detached. Then it felt like it had gone a bit mushy. My vision blurred, my motor skills nearly disappeared, and I nearly blacked out. I sort of leaned against the ATM, and then stumbled to the side of it. I tried to shake it off -- I've had dizzy spells before, but this was nothing like that.
