Been lucid 3 nights in a row!

But the problem is, every time I go to complete a goal, I say "mission accomplished!" I remember trying to stay in the dream to ask my grandmother why she tried to perform inception on this guy, and she said she liked it. My goal was to find out why, and when I did, I don't lose lucidity, but I just have nothing else to do, like I forget my other goals. It's really annoying >.<

P.S. I tried the finger through hand reality check to stay lucid to ask her, and it feels VERY weird. I don't suggest it :P

Summary: How to last through a lucid dream for more than one goal, rather than feeling so satisfied I just become bored until I become unlucid?

Um... hm... never had this problem, personally. Don't be so satisfied when you complete it? :P I guess it would turn into a matter of awareness. In real life, after finishing a goal, I assume you wouldn't have a problem remembering your next. So in the lucid dream try to increase awareness. Just a guess here.
