That means doing it even when awake.
The reality check that worked best for me was pinching my nose and seeing if I could still breath. If you do that multiple times a day out of habit, then eventually you'll do it while dreaming and realize you're asleep.
That's the easy part. You can briefly become lucid every single night. The hard part, for me at least, is hanging on to the dream. I usually wake up shortly after realizing.
Makes sense about the waking up part. I have realized I was dreaming in the past, and immediately woke up almost every time. Usually this happens when I reason something out as being impossible, or destroy the premise/backstory of my dream by really thinking about it.
When I was a kid, I had a frustrating dream where I did realize I was dreaming, yet was "stuck" in the dream and could not wake up. I kept straining to wake up, and it didn't occur. I was actually in kind of a panic about it. Once I knew it was a dream, I didn't want to be there anymore. Nothing bad was happening in the dream. I was at some unfamiliar house in some unfamiliar yard, but there was nothing otherwise stressful or traumatic. But I couldn't get out of it, and I was seemingly stuck there for hours (I actually wasn't, but it felt that way).
Given that experience, I don't think I would want to lucid dream. I would probably find it more stressful knowing that I was trapped in a fake reality than I would find it enjoyable that I could basically do whatever I wanted with no consequence. Also, I'm afraid some of the fun of creating "good" scenarios would disappear if you knew they were fake. When I would dream of playing on the Dodgers or Lakers, it was only fun because I thought I was playing on the real teams in front of a real crowd. When I am flapping my arms and flying over some kind of beautiful landscape or out in space, it's only fun because I think I'm really seeing these things. If I know I'm just imagining it, it might not be that interesting.
I think the biggest application of lucid dreaming is sexual. If you could envision a lifelike sexual encounter with a fantasy girl, that could be fun, even if you knew it wasn't real.
