Did I have a premonition?

Tonight I went to my high school's football game. My sister picked me up, the place was packed. As we were leaving the parking lot, I swear to god this thought went through my mind, "There's going to be a car crash and someone's going to die tonight." I don't know why the thought entered my mind, but it did. About 2 hours after we got home, I'm watching the Yankees game and my sister comes downstairs. She tells me there was a car crash in the parking lot and a girl who's name I will not say died. Other people died too, apparently. It's one of the most devastating things to ever happen to our school. I am deeply saddened by it, as everyone is. But should I think anything of that thought I had?
