What does this dream mean?

Okay so I was in my Dads parents town and the sky was green with black clouds and a tornado touched down and we were in the car so we started going really fast like 100 mph and then it started going to the city where I live which is really close but not the same town and then I woke up and now theres black clouds and thunder, lightning, and rain could this have been a premonition no one knew it was supposed to storm bad yesterday it was just on the weather channel today that its supposed to storm bad
