Try to continue your dream

I had a weird dream which I was with my close friend and a bunch of new ones, we were on a mine car on a roof of a house (yeah a mine car on a roof of a house) then out of nothing a random jerk pulled the lever and all of the sudden my new friends desapeared lasting only me and my best friend.
The mine car flyed in the city and when we realized that it started falling slowly but going somewhere weird, my friend Said:
"We should jump! No one knows what is over there! There is a high probability of dying if we jump, but the probabilitys to survive are bigger then if we stay, plus if this unknown place is dangerous, we will have a painful death"
I just replied: "I am not sure, I think we should risk and stay"
But before I could complete the sentence he jumped, when he jumped the mine car rushed really fast and crashed on a floating place I could see the city from there but no one say that place before, it was a sunny place, with only the sky and a really green grass, nothing more nothing less. Then I woke up, now I have so may questions, what would happen if I jumped? Did my friend survived? Where did he land? Will I die in that place? Who was the person who pulled the lever? And a lot more
I tried to at least continue the dream, however I was not able to do this.
