I had a very scary dream, what does it mean?

Well I just woke up from a long, very scary dream. It started when my dad told me and my mom to get into the car, so we packed up the dogs and left. Later on we stopped at a restaurant and I asked where we were going. My mom then told me, "We are going to get put down so we can go to Heaven and live as a family." I know its weird, and stupid, but my all time worst fear is dying. So we were back in the car and I was crying and begging for then to turn around, but my dad kept saying, "The world is going to end on Friday anyway." It doesn't sound scary, but if you witnessed the details, you would be very scared. Can someone please explain if this means anything?
