Yeah congratulations, it's an amazing thing to be able to achieve. Too bad it didn't last as long as you'd hoped. Typically it doesn't. I find that the more I combat what the dream is supposed to be for, the shorter the time frame I have being lucid. So just a tip, it might work for you but the next time you go lucid it may be good to play along with the dream, maybe to go back and talk with those people. I sometimes weave my lucidity into the storyline, like I'll remarkably be doing things I shouldn't but then I say I've just discovered super powers or something like that and the dream tries to adjust to fit that rather than just booting me.
Anyway, no matter the length of the experience they're always special. Sometimes I spend it all at once and do something epic so I can talk...
