What could this dream mean?

In that night,I woke up from my bed,then I was doing something and then I went back to bed.Then,I had a dream...In the beginning of that dream I was speeding in a fast car(like Mclaren F1 or Koenigsegg ccx).At first I viewed it from the bumper of the car,seeing only the road,then it changed to first person view,and I was able to see the pit of the car,I've seen my own hands.I was using the steering wheel and then I saw myself shifting a gear.I was going on a road that went upwise and then I was going on a cranky road,turning left and right multiple times,then I arrived at place.It looked like a big cave or something,and then I saw my hands.I saw that I have gloves on my hands,and then I had a vision like if I have consumed hallucinogens.Then I screamed:This is a dream!And then I said:This is a wake back to bed lucid dream.Cool!So now I'm in a lucid dream.Then I went deeper in that cave and then I saw something like an Aurora.And then,I don't remember...I think it ended there.But I know I used to turn around sometimes in the dream because I know that if you turn around in a lucid dream you try to prevent it from ending.
