It happen around July, 2008. I was on my way to work around about at 6:30 a.m. It was really clear that morning. I was about 10 minutes away from where I worked when drove into some fog. I thought it was a little weird because there was no fog anywhere else and there wasn't a river or anything to cause fog in that area.
When I drove into the fog, it was maybe about a minute in when I saw lights flashing through the fog. As they got closer I could see that it was maybe an ambulance. I slowed down a little, waiting on it to pass. It seemed to take a while for it to get to me. I thought it might have stopped. Then in a few seconds the ambulance appeared in front of me. When it started to pass me, it seemed to move in slow-motion, and while it was passing it never made a sound. No sounds of the engine or any sounds on the road. There was nothing.
After it passed, I rode out of the fog and arrived right in front of the parking lot of my job. I was 10 minutes away from my job and I got there in two! I don't where that time went, and I don't know what that was in the fog.
