Welcome to LD4all Feba (you’re member 9999, don’t you feel honoured? =p) I moved your topic to Quest, since I think it fits better there 
Like Gyth said, it was a lucid dream, since you knew you were dreaming. So congratulations for that, and that for a first try. That is really good.
The thing at the end seems just as waking up normally. Sometimes when you have a lucid dream you already feel your physical body before you wake up. I’ve had that too, and I know there are a lot of other people out there who had it too. If you want to know techniques to stay in the dream you can read this topic. It basically comes down to the fact that you can rub your hands, focus your awareness, grab something, or something along that.
