Somebody please tell me what just happened?

I hadn't eaten much all day besides a egg mcmuffin and 3 pieces of fruit. It was 5 when I driving home and I started feeling disorientated. My heart started beating rapidly and my breaths were short and rapid. I felt like there was a tight headband around my head and I couldn't focus. At one point I thought I was dreaming but a supernatural force (I call him GOD) took me home somehow. What just happened? I ate a hearty meal when I got home and I feel better but I still feel a little ill. What should I do to make me feel better? Thanks for listening =)
