Dream of building

Somebody was driving and had to leave because he had to warn my school that radiation would burn part of the building so i had to take over the wheel. I am a beginning driver so i stopped the car and got out instead as the car was flipping over on its side. All of a sudden, everything started to lift about 5 ft off the ground, everything was floating like gravity had failed. Once it stopped, i ran to the school. It was a different environment there now while some parts of the building we burnt.
