Your dream was intense, seems indeed like a whole movie :))
What is great is that you didn't want to wake up, but left the dream as a winner. That is maybe indeed because you don't give up things easily, and you are competitive. How positive outcome of the situation, all the tunnels and in the end you found the exit from the bad situation! Cool!
I like dreams and especially when I remember them well. Recently I had a super detailed dream and I was so happy that I remembered it very well the next morning :)
