I had a similar experience. I wouldn't say it was demonic or anything, just odd and creepy.
I was on the way home from work one night, it was late, around midnight, and the fog was so thick that I had to slow down to 20mph on a 55mph highway.
This is in a very rural area of backwoods northern Alabama, on a road that cuts through hills and forest areas, so there's never anyone around at
Anyways, I was driving slowly down that road when all of a sudden I saw a person hauling BUTT on foot down my side of the road! He/she was running
towards the direction I was driving. I had to swerve to avoid hitting him/her. Didn't get a good look at this person, he/she quickly faded into the
fog behind me. That was strange in and of itself, but then, up in the left lane of traffic, right in the road there was a man (looked to be in his
30's, balding black hair, white guy, mid to large build, about 6 foot tall) in a black business suit just standing there. He stared at me as I drove
slowly up the road with the meanest look on his face, like he just wanted to pop me like a pimple. As I got right up next to where he was he started
walking toward my car! I gunned the gas pedal, fog be damned, and passed him by, I look in the rearview mirror and he's running down the road
I sped on home and that was that. The whole experience had a dreamlike quality to it.
Sure was strange. Nothing in the paper the next day about anything happening in that area, I guess it could have been any number of things that I
witnessed from a drug deal to a murder about to occur. I'm not really a believer in "paranormal" things, but I guess I can say that the look that
guy was giving me did "feel" like pure evil. I guess I'll never know what that was all about!
