> But during my lucid dream, there's absolutely no way of knowing. Curious if this is universal or if other people who lucid dream do always know the details of their actual true reality -- their age, what city and home they live in, current job, etc.

This is referred to as different levels of lucidity. While lucidity is technically a binary state (know or don't know), it can sometimes be better described as a spectrum where you can "know" but not fully understand what it means.

Some levels you might think of are: Thinking it's 100% real. Having a "feeling" something is off. "Feeling" its a dream. Consciously expressing its a dream. Understanding its a dream. And then actually understanding the full consequences that its a dream.

Usually this comes down to a matter of thought clarity, not memories. If you understand its a dream, then it has no consequences period. Even if you think the worry is real, you still can't affect the physical world in a dream. Perhaps you could try practicing/studying in your dream, and writing stuff down when you awake, or just forcing yourself awake in order to study/practice more. However, outside of that, nothing you do affects the real world, so there's no logical reason to worry about it, even if you don't have the memories to understand "oh its entirely fabricated".

As for others, it obviously depends on the dream, as each have their own level of lucidity, but I can personally say I know basic facts that don't require any specific memory, like my dad being alive is impossible, because he passed. I probably couldn't take a quiz though. I can also remember specific goals, though again, more as a natural feeling than a specific memory.

If you want to try to get out of the dream's story, you have to be willing to accept that if something is impossible, no story can explain it; it has to just not be real.
