Weird Dream

Last night I had a weird dream. Here are the details I can remember.

1. Watching the Sopranos with my family and they had a new final episode where it turns out everything was a dream in Tony's head, and he really was this Kevin Finnerty guy.
2. Me and my brother had a conversation about how weird it would be to wake up and find that everything you just experienced was a dream.
3. My son and I had to be somewhere so Randy offered to drive us.
4. His "car" was a bed mattress with no box springs. We laid the mattress down on the road and it started to go.
5. Cars were honking and passing us frantically.
6. As we accelerated down hills, I could feel myself start to slide off the bed. I had to grab my son a couple of times to keep him on the bed.
7. We passed a car repair shop and my brother noticed his buddy's car in the shop.
8. Shortly thereafter I proceeded to get up and carry my son and start walking.
9. Just then a gang of bikers came walking by and started inspecting the mattress and commenting, "It ain't go no wheels!"
10. As I walked, I could feel my legs burn when I realized it could be miles before I reached our destination.
11. We were about to get back in the "mattress mobile" when I woke up.

What does it all mean?
