Mine is somewhat similar to Patrick's story. I remember it clear as daylight...
What happened (Reality, not a dream): It was about two years ago. I had recently visited Oklahoma (I have family down there) and got caught in a tornado warning around Tulsa. The tornado touched down under three miles or so from where I was. A town where we were planning on stopping for the night was demolished by this tornado (I'd guess it's an F3 or so). Obviously shocked, yet happy that we missed that exit, I didn't know what to think. Then about a week later this dream happened...
Dream: It was late July. A rather muggy summer day with a high around 90°. A little hot for Michigan's standard summer, but not out of the question. Off to my west over the Great Lakes, huge cumulonimbus clouds were brewing up. I turned the TV on, and sure enough there was a WeatherStar III scrolling a tornado watch. As I am the kind of guy who loves weather, my adrenaline started rushing as I was excited for this event. A few hours later, the WeatherStar III started scrolling a tornado warning for my county... with the tornado over the MSU campus if I remember properly. When I looked out my window, the clouds were a greenish-yellow tint, especially to my west. I got in my car (Funny because I don't even own one yet, but I can dream
) and started driving west in hope of seeing the tornado. The tornado sirens started to go off around me and it started to hail, then to my east, I saw the tornado (I was parallel to it at the moment). I remember it ripping buildings apart and throwing buildings around like a child throwing toys around. The tornado started moving towards me with the notorious freight train sound. When it got about 50 yards away, I woke up and noticed that I sweat a puddle in my pillow
Quite the dream like I said, and it sticks out.
