It is true that this topic has been taught a lot of times, but it is true, anyways, that we must help them no matter what....every person is different.
when you doubt about your lucidity, then it wasn't lucid..
doesn't matter if you, in the dream, say "oh I'm lucid, I can fly", because that's wasn't conscious...

try this.
think what would you do if you know you are dreaming, I mean, you come completely lucid, what would you do?
that's the principal question to all the...eh...questions...
