What could this dream mean?

I had a dream I was with two or three of my closest friends and we were camping outside of my grandma's house (like I had actually done the previous weekend), except this time it was outside of her club house. I was mad that I couldn't just go inside the club house and sleep because there were beds where it was warm. *I felt this way last weekend about being so close to her house, so I'm not sure if this means anything*. We snuck into her house to get on the computer. Me and my friends got on a website that was supposed to calculate the exact date of your death - the minute, hour, day, month, and year. Mine was scheduled to be at I think either 12:33 or 12:34 the following day. We just kind of laughed it off, but the next day at 12:30 I was riding in a car with the same people, but the youth leader of a church camp I went to two years ago (and hadn't seen since then) was driving us. I remembered the website and put on my seat belt a few seconds before we went around a curb. A car was going too fast and swerved into our lane as we were going around the curb. Our car ran off the road and everything started going in slow motion. My friends and I all managed to jump out in the ditch and no one was hurt.
