Wow. That sounds pretty intense, I've never blacked out before. It must have been really scary
I've experienced voices while I'm driving too though, last year when I'd drive to my music lesson and to jam sessions, I always had to pass over this one bridge, and every time voice told me to drive off. Most of the time it was yelling in my head, a few times though it actually felt like the voice was whispering in my ear.
I take the train and the subway everywhere now though. Voices still tell me to jump in front of the train every time it comes rolling through the station.
