I tried committed suicide in my dream and guess what happened!!

last night I did it,I walked over to a window ledge and jumped from a 300ft window.
when I hit the ground, I just saw a white haze then the haze cleared. surprised as shit I was not hurt I got up and looked around and everything was fine! but the dream world was different.
I was now aware I was in a dream. I then went back up to the window that I had jumped from before and on the way up I helped other people jump and told them It would be ok it was just a dream. so they jumped one after another.

I was like a kid in a water park,but something was different with me. I could fly and make things materialize. I lifted huge objects with my mind. Then a car pulled up and a girl got out, walked up to me and said "I have been watching you and I think you are good, follow me I want to show you something" she lifted off the ground and hovered I was thinking 'what is going on here only I can do this.'we flew up above the clouds and she yelled "now try to keep up " we both flew supersonic speeds it was a very cool feeling to finally do that. flying was getting easy in dreams, but I was helped to believe it was possible to go even faster by this girl.

I know now I am mastering the dream state but why, why now and who was this girl I never saw anyone do what I can do in a dream before.
I have been lucid dreaming for years, but this dream was the first of this kind.
