What the heck happened to me?

So I was about an hour out, on my way home and then I guess I zoned out a little bit but all of a sudden, I realize I'm going in the opposite direction without ever consciously doing so, the clock that read 1:40ish in the afternoon now said 20 or so after four and it was getting dark out! What the HECK?
