I frequently have lucid dreams, in that I'm entirely aware of that fact that I'm dreaming while in the dream. What I find interesting, however, is that if I have a dream I forgot to study for my test, or I'm naked at school because I left my clothes somewhere else, or the school play starts tonight and I haven't memorized a single line... the fact that I know I'm dreaming doesn't help at all . Because the problem is…
I have lucid dreams somewhat frequently since I was maybe 8 or 9 after I started getting prescribed medication to help me sleep (initially it had been almost nightly, but it reduced over the years to the point where it happens maybe a couple times a month now a couple decades later), and generally I do remember the details of my life in lucid dream, but I sometimes have trouble determining whether they're details of my life in the past or the present. If in my dream I'm back at school, it's usually not the case that I don't remember graduating, getting a job, and moving; often times I have a vague sense that all of that had happened, but then some issue was discovered with my records that forced me have to go back and retake a class or two. (This obviously is pretty implausible, but dream logic isn't always airtight!)

Having real world knowledge doesn't always mitigate the "issue" in the dream though; in my lucid dreams, I don't have any control over what happens beyond my own actions, so a teacher expecting me to hand in some assignment won't generally accept "it's a dream so I don't have to" as an excuse. There is a way that knowing that I'm dreaming helps though; I can just choose to wake up! I'm not sure whether being able to forcibly wake up is typical or not for people dreaming lucidly, but I've never had much trouble doing it. Sometimes I'll end up back in the same scenario if I fall back asleep again after though, so it might end up being worth it to suffer through the imaginary misfortune to get the real world benefit of sufficient sleep.
