I've heard from several sources that the time in real life is the same in a lucid dream, and it sounds plausible enough.

But then I remembered a lucid I had last August, before I was interested in LDing, that seemed to last for weeks when I was in it. When I woke up, I wasn't quite sure how long I had been in it, but it was long enough for me to almost completely forget about the real world.

I know my sense of time in that dream was certainly distorted, but can you manipulate your own sense of time to effectively prolong a LD for a very long period of time? (And no, I'm not talking about time machines. That's a different story.)
